Description

Technical Field

[0001] The present invention relates to the technical field of the structural design of coal mine tunneling beam-lifting machines, and particularly relates to a beam-lifting machine. Background Art

[0002] Since roadheader is usually used for excavation operations in coal mine roadway driving faces in China, after the roadheader works for a certain distance, the power supply of the roadheader is turned off and locked. After the excavation stops, arched metal support materials, anchor bolts, anchor cables, etc. are used to reinforce the roadway. Due to the large volume of the roadheader and the narrow roadway space, it brings great difficulties to the roadway support work. Therefore, the installation speed of the roadway support work in the driving face directly affects the driving speed of the driving face, and also affects the treatment and start-up of the return airway. It is the main factor affecting the balance of mining and excavation succession and restricting the safe and efficient development of the mine.

[0003] Currently, when steel structure supports are used in coal mine underground driving roadways in China, due to the narrow roadway space and the heavy weight of the steel structure components themselves, it is very difficult for manpower to install them in place.

[0078] The beam-raising machine of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0079] like Figures 1-14 As shown, the beam-loading machine includes:

[0080] Sliding device 1 that slides along the coal mine tunneling face (during the tunneling process, a monorail is installed at the top of the tunneling face, and sliding device 1 slides along the monorail).

[0081] 2. A telescopic lifting arm that can also perform rotation and lifting functions;

[0082] Lifting claw 3, which provides support for the metal support of the tunneling face.

[0083] A lifting arm 2 is connected to one side of the sliding device 1, and a lifting claw 3 is connected to the other end of the lifting arm 2. The sliding device 1 drives the entire device to the required position. The lifting claw 3 limits and lifts the metal support. Furthermore, the extension, retraction and rotation of the lifting arm 2 lifts the metal support to the designated position, thus fulfilling the lifting function of the metal support, assisting workers in construction, improving work efficiency, and avoiding difficulties for workers in construction.

[0084] like Figure 1 and Figure 3 As shown, to ensure the lifting effect and prevent the metal support from slipping during the lifting process, thus improving the safety of construction, the lifting claw 3 includes: a lifting body 31 for adjusting the angle and providing support; and a locking claw 32 for limiting the metal support. The locking claw 32 is fixedly connected to the upper side of the lifting body 31, and one side of the lifting body 31 is hinged to the lifting arm 2.

[0085] In one embodiment, a hydraulic support is provided between the side of the lifting body 31 and the lifting arm 2. The extension and retraction of the hydraulic support allows for adjustment of the angle of the lifting body 31, which can conveniently support and lift metal.

[0086] like Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, to further improve the limiting effect and avoid the risk of falling during the lifting process due to construction vibration and the relatively high lifting height, the lifting claw 3 also includes a limiting claw 33 for limiting and fixing the metal support. The limiting claw 33 is hinged to the upper side of the lifting body 31, limiting the support to be lifted (the aforementioned metal support) between the limiting claw 33 and the lifting body 31. Through the further limiting effect of the limiting claw 33, the limiting effect on the metal support is ensured, improving the safety performance of the construction.

[0087] like Figure 6 , Figure 7 and Figure 8 As shown, the limiting claw 33 includes: a limiting beam 331 that blocks and limits the position of the metal support, a connecting beam 332 that connects and drives the limiting beam 331, and a pressure beam 333 that drives the entire limiting claw 33 to rotate after being subjected to the downward pressure of the metal support.

[0088] At the upper and lower ends of the connecting beam 332, a limiting beam 331 and a compression beam 333 are respectively connected, so that the limiting beam 331, the connecting beam 332 and the compression beam 333 enclose a "匸"-shaped structure. The metal support is limited inside the "匸"-shaped structure to prevent the metal support from slipping above the unobstructed claw 32 when it is impacted or vibrated violently. After being blocked by the limiting beam 331, when impacted or vibrated violently, the metal support instantly lifts, and the limiting beam 331 blocks the metal support from bouncing, ensuring that the metal support and the lifting claw 3 are integrated, reducing the possibility of accidents.

[0089] In order to facilitate the upper opening after the limiting claw 33 rotates, making it convenient to take out the metal support, the connection between the compression beam 333 and the connecting beam 332 is hinged to the lifting body 31; when the limiting claw rotates outwards, the upper side is in an open shape, and the metal support is taken out from the upper part.

[0090] In order that during the process of taking out the metal support, the limiting claw 33 can rotate outwards under the action of gravity, or during the process of taking out the metal support, the limiting claw 33 is slowly pushed by the metal support, driving the limiting claw 33 to rotate, ensuring the taking out of the metal support. The center of gravity of the "匸"-shaped structure formed by the limiting beam 331, the connecting beam 332 and the compression beam 333 is biased towards the connection between the limiting beam 331 and the connecting beam 332; when the compression beam 333 is compressed and pressed against the lifting body 31, the perpendicular line of the center of gravity of the "匸"-shaped structure extends beyond the tail of the compression beam (333), causing it to rotate outwards under the action of gravity.

[0091] Since the distance between the perpendicular line and the compression beam 333 is not too far due to the limitation of the mechanism, the limiting claw 33 rotates outwards slowly under the action of gravity. When the metal support is impacted or vibrated violently, the metal support moves quickly, and the rotation of the limiting claw 33 cannot respond quickly, so the limiting beam 331 is still on the upper side of the metal support, blocking the metal support.

[0092] In a preferred embodiment, an anti-slip material is coated on the lower bottom surface of the limiting beam 331. When the metal support vibrates violently and acts on the limiting beam 331, due to the action of the anti-slip material at the bottom of the metal support and the limiting beam 331, the resistance to mutual sliding is increased, ensuring the limiting effect on the metal support. When the metal support slowly rises, due to the action of gravity, the entire limiting claw 33 rotates self, and the metal support can be smoothly taken out from inside the lifting claw 3.

[0093] The tail of the compression beam 333 is: the connection between the compression beam 333 and the connecting beam 332.

[0094] The head of the compression beam 333 is: the end of the compression beam 333 far from the connecting beam 332.

[0095] In the existing technology, the most commonly used metal support cross-section is an isosceles trapezoidal structure. Both the claw 32 and the limiting claw 33 are designed with an inner cavity isosceles trapezoidal structure to fit and connect perfectly with the metal support. Of course, the height of the inner cavity of the isosceles trapezoidal structure of the claw 32 and the limiting claw 33 must be higher than the height of the metal support cross-section to ensure that no interference occurs during the rotation of the limiting beam 331.

[0096] In particular, the tilt angles of the left claw 321 and right claw 322 of the clamping claw 32 must be the same as the tilt angle of the lower inclined surface of the metal support to ensure that the left claw 321 and right claw 322 can fully fit and support the metal support during the process of supporting the metal support, avoiding stress concentration. During the rotation of the limiting claw 33, the rotation angle should not be too large, otherwise the pressure beam 333 may tilt too high. During the process of lifting the metal support into the clamping claw 32, the position of the pressure beam 333 pressed down by the metal support may not be on the upper surface of the pressure beam 333, which may prevent the pressure beam 333 from rotating downward smoothly. Therefore, a support column 34 is fixedly connected to the edge of the lifting body 31, and the upper side of the support column 34 supports the rotation of the limiting claw 33. When the limiting claw 33 rotates outward and the support column 34 limits and supports the limiting claw 33, the upper end of the limiting beam 331 rotates to the outside of the upper end of the clamping claw 32. That is, during the rotation of the limiting claw 33, the head of the pressure beam 333 does not exceed the left claw body 321 or the right claw body 322 of the chuck 32. When the metal support enters the chuck 32, it first contacts the upper surface of the pressure beam 333. The pressure beam 333 is pressed and rotates downward, thereby realizing the rotation of the limiting claw 33 to limit the metal support inside the limiting claw 33.

[0097] like Figure 4 and Figure 5 As shown, there are at least two limiting claws 33; the limiting claws 33 are arranged in a staggered manner on both sides of the lifting body 31; the staggered arrangement can ensure that the metal support is completely limited and wrapped during the closing and rotation of the limiting claws 33, thus ensuring the limiting effect.

[0098] When the pressure beam 333 is compressed and pressed against the supporting body 31, the end of the limiting beam 331 away from the connecting beam 332 extends beyond the vertical plane of the supporting body 31 along its length. That is, on the upper side of the metal support, it is in a fully closed state, ensuring the limiting effect.

[0099] like Figure 4 As shown, two limiting claws 33 are provided, one on each side of the lifting body 31, to improve the limiting strength of the limiting claws 33 and increase the size of the constraint surface on the metal support. The width of the limiting claw 33 is 1 / 4 of the distance between the two claws 32, and the limiting claw 33 is at its widest extent while ensuring that installation and rotation are possible. Figure 5 As shown, there are three limiting claws 33, one wider one in the middle and two narrower ones on both sides.

[0100] like Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the chuck 32 includes a forked left chuck body 321 and a right chuck body 322, and a fixed arm 323 connecting the left chuck body 321 and the right chuck body 322. The lower ends of the left chuck body 321 and the right chuck body 322 are fixedly connected to the two ends of the fixed arm 323, respectively. The left chuck body 321 and the right chuck body 322 are respectively inclined outwards, forming an open structure to facilitate the entry of the metal support into the chuck 32. To ensure the auxiliary support function of the limiting chuck 33, the inclination angle between the connecting beam 332 and the pressure beam 333 is the same as the inclination angle between the left chuck body 321 and the fixed arm 323; or the inclination angle between the connecting beam 332 and the pressure beam 333 is the same as the inclination angle between the right chuck body 322 and the fixed arm 323; ensuring that the left chuck body 321 or the right chuck body 322 is flush with the connecting beam 332, thus providing auxiliary support for the metal support.

[0101] To facilitate rotation and maximize the rotational space of the limiting beam 331 during rotation, the limiting claw 33 is positioned at its maximum opening during the metal support's entry into the limiting claw 33, ensuring the metal support is fully closed within it. The hinge axis connecting the limiting claw 33 to the lifting body 31 is located at the center of the connection between the left claw body 321 and the fixed arm 323, or at the center of the connection between the right claw body 322 and the fixed arm 323. When the pressure beam 333 is compressed and pressed against the lifting body 31, the inner wall of the connecting beam 332 is in the same plane as the inner wall of the left or right claw body 321. In other words, the connecting beam 332, along with the left and right claw bodies 321 and 322, supports the metal support, increasing its support strength.

[0102] The inner wall of the connecting beam 332 refers to one side of the inner cavity enclosed by the limiting claws 33;

[0103] The inner wall of the left claw body 321 or the right claw body 322 refers to one side of the inner cavity of the forked claw 32.

[0104] In a preferred embodiment, such as Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the height of the pressure beam 333 is the same as the thickness of the fixed arm 323, so that when the pressure beam 333 is pressed against the lifting body 31, the upper surface of the pressure beam 333 and the fixed arm 323 are in the same plane, jointly supporting the metal support. At both ends of the claw 32, auxiliary support columns are fixedly connected to the upper surface of the lifting body 31. The height of the auxiliary support columns is the same as the thickness of the fixed arm 323 and the pressure beam 333, together supporting the metal support. Due to the limitations of the limiting claw 33 structure, the center of gravity shift will not be too large. Therefore, in order to ensure that the limiting claw 33 rotates with the metal support during the removal process, it is sufficient to provide an attractive force between the pressure beam 333 and the metal support. Therefore, a magnetic groove is provided in the middle of the pressure beam 333, and a permanent magnet is installed inside the magnetic groove. Since metal supports are usually made of steel or iron, the permanent magnets have a certain magnetic attraction to the metal. Of course, the magnetic attraction does not need to be too large. It is necessary to ensure that the metal support can separate from the pressure beam 333 when the metal support is impacted or violently vibrated.

[0105] To further facilitate the metal support's entry into the limiting claw 33, and to ensure smooth downward pressure on the pressure beam 333, avoiding contact with the end of the pressure beam 333 which could prevent the pressure beam 333 from moving downward smoothly and causing the limiting claw 33 to become stuck, the end of the pressure beam 333 away from the connecting beam 332 extends beyond the edge of the supporting body 31, and the end of the pressure beam 333 away from the connecting beam 332 is bent downwards in an arc. When the limiting claw 33 rotates outwards, if the rotation angle is large, when the head of the pressure beam 333 enters the cavity, because the entire head of the pressure beam 333 is bent downwards in an arc, the pressure on the pressure beam 333 is still downwards when the metal support contacts the pressure beam 333, thus further ensuring the downward rotation of the limiting claw 33.

[0106] To better ensure the limiting function of the limiting beam 331, the limiting beam 331 and the compression beam 333 are arranged in parallel. When the metal support is impacted or subjected to severe vibration, the limiting beam 331 is subjected to the impact force of the metal support perpendicular to the limiting beam 331. Since the limiting beam 331 is also subjected to the tensile force of the connecting beam 332, it ensures a certain limiting effect on the metal support and prevents the metal support from flying out of the cavity.

[0107] To increase the eccentricity of the entire limiting claw 33, thereby ensuring further shift of the center of gravity and facilitating the rotation of the limiting claw 33, the connection between the limiting beam 331 and the connecting beam 332 is rounded, and the connection point protrudes outward at the rounded transition.

[0108] In one embodiment, to increase the degree of eccentricity, a gravity groove is provided on the outer wall of the arc transition section. A counterweight 334, for example a lead block, made of a material with a density greater than that of the limiting beam 331, is fixedly connected inside the gravity groove. To ensure balanced support of the metal support and stable force distribution during lifting, two claws 32 are provided, located at opposite ends of the lifting body 31.

[0109] In a preferred embodiment, such as Figure 5 As shown, three limiting claws 33 are provided; one is located in the middle of the lifting body 31, near the lifting arm 2; and one limiting claw 33 is located near each of the two clamping claws 32, with the two limiting claws 33 near the clamping claws 32 respectively located on the side of the lifting body 31 away from the lifting arm 2. The width of the limiting claw 33 in the middle is greater than that of the limiting claws 33 at both ends, ensuring balanced strength on both sides. In a preferred embodiment, multiple limiting claws 33 can be evenly provided on both sides of the lifting body 31 to form multiple limiting rod structures, which work synchronously to ensure the limiting effect on the metal support.

[0110] like Figure 1 , Figure 2 , Figure 10 , Figure 11 , Figure 12 As shown, the sliding device 1 includes: a sliding frame 11 for supporting and connecting; a connecting plate 12 for limiting and connecting the position of the sliding frame 11; a drive wheel 13 for driving through friction with the monorail; and a braking device 14 for braking through friction with the monorail. Two sliding frames 11 are arranged opposite each other, and their ends are connected by the connecting plate 12 to form a frame structure. A drive wheel 13 is connected to the upper side of each sliding frame 11, and the two drive wheels 13 are clamped to both sides of the monorail. A braking device 14 is provided at each end of each sliding frame 11, and the braking end of the braking device 14 presses against the monorail, thus satisfying the functions of driving and braking.

[0111] To facilitate the connection of the sliding frame 11 to the drive wheel 13 and the interconnection between the sliding frames 11, the sliding frame 11 includes: a frame body 111, a horizontal plate 112 connecting the drive wheel 13, and a protruding plate 113 connected to the connecting plate 12. The horizontal plate 112 is located in the middle of the frame body 111, and the drive wheel 13 is connected to the upper surface of the horizontal plate 112. The drive wheel 13 is located on the upper side of the horizontal plate 112. During the pressing and driving process of the monorail hoist, the monorail hoist exerts a reaction force on the drive wheel 13. The horizontal plate 112 located in the middle ensures the force balance of the entire frame body 111, guarantees the stability of the entire device, and extends its service life.

[0112] The frame 111 extends from both ends with protruding plates 113; two connecting ports 121 are opened through the connecting plate 12, and the protruding plates 113 extend along the connecting ports 121. The protruding plates 113 extending from the two connecting ports 121 of each connecting plate 12 are connected by a tensioning member 4; the connecting plates 12 set at both ends of the frame 111 ensure the connection of the frame 111.

[0113] To improve the tensioning effect, especially to provide not only tension but also a certain degree of cushioning, the tensioning component 4 includes: a clamping device 41 for pressing and fixing, a spring-loaded device 42 for cushioning and supporting, and a connecting rod 43 for connecting. The connecting rod 43 passes through the convex plate 113 (the convex plate 113 has a through hole). The spring-loaded device 42 is provided for elastic support between the convex plates 113. The clamping devices 41 are respectively provided on opposite sides of the convex plates 113, so that the clamping devices 41 press the convex plates 113 together, driving the two drive wheels 13 to move closer together. The spring-loaded device 42 supports the convex plates 113, providing a certain auxiliary support for the drive wheels 13. Under the premise of meeting the clamping requirements, it avoids excessive clamping force on the drive wheels 13, which could cause wear. Due to the support of the spring-loaded device 42, the clamping device 41 can provide a large constraint force, avoiding the defect of unstable friction and unstable driving during the drive of the drive wheels 13 due to insufficient constraint force.

[0114] To ensure the clamping effect, the clamping device 41 includes: a clamping spring 411 for buffering the clamping action; a clamping washer 412 that mainly provides clamping force to the clamping spring 411; a buffer pad 413 that provides certain deformation and misalignment requirements; a misalignment pad 414 that allows for clamping action when misaligned; and a clamping bolt 415 for clamping and fixing. The clamping bolt 415, misalignment pad 414, buffer pad 413, clamping washer 412, and clamping spring 411 are sequentially arranged at the end of the connecting rod 43. A threaded groove is provided on the outer wall of the end of the connecting rod 43 to cooperate with the clamping bolt 415. The clamping spring 411 is pressed against the surface of the protruding plate 113.

[0115] To prevent vibration-induced misalignment, the vibration force on the drive wheel 13 is buffered, ensuring both buffering and constraint. The misalignment pad 414 includes an upper pad 4141 and a lower pad 4142. The lower surface of the upper pad 4141 has a circular arc protrusion, and the upper surface of the lower pad 4142 has a circular arc groove. The radii of the circular arc protrusion and the circular arc groove are the same, and the circular arc protrusion fits inside the circular arc groove. A misalignment hole 4143 is formed through the upper pad 4141 and the lower pad 4142, through which the connecting rod 43 passes. The diameter of the misalignment hole 4143 is larger than the outer diameter of the connecting rod 43. When the drive wheel 13 vibrates, the vibration is transmitted to the frame 111, causing misalignment. Because the misalignment pad 414 can provide a certain degree of misalignment locking, it ensures constraint and fixation within a certain misalignment range. The large diameter of the misalignment hole 4143 meets certain misalignment requirements.

[0116] To further provide a certain deformation range, satisfy the cooperation with the misalignment pad 414, further reduce the impact on the clamping pad 412, and ensure the clamping effect of the clamping pad 412 on the clamping spring 411, the buffer pad 413 has a deformation hole 4131, through which the connecting rod 43 passes. The diameter of the deformation hole 4131 is the same as the diameter of the misalignment hole 4143. That is, the clamping spring and the clamping pad are fixed in position, the clamping pad 412 clamps and fixes the clamping spring 411, and through the misalignment of the buffer pad 413 and the misalignment pad 414, the clamping effect can still be satisfied within a certain misalignment range.

[0117] In order to improve the constraint effect on the frame 111 and ensure the stable support of the drive wheel 13, protruding plates 113 extend from the upper and lower sides of both ends of the frame 111, and the protruding plates 113 are connected to the connecting plates 12 respectively to ensure the constraint effect on the frame 111.

[0118] The connecting plate 12 includes a front plate and two rear plates. The front plate is connected to one side of the frame 111, and the protruding plates 113 on the same side of the two frames 111 extend out of the front plate and are connected. A hinge plate is provided in the middle of the front plate, and the hinge plate is hinged to the lifting arm 2. In order to provide a connection position with the lifting arm 2 and to avoid interference with the tensioning member 4, so as to ensure the function of the whole device, the front plate is larger in size and larger than the two rear plates. The hinge plate is connected in the middle space of the front plate to realize the hinge connection of the lifting arm 2.

[0119] The rear plate is connected to the other side of the frame 111, and the protruding plates 113 of the two frames 111 are respectively inserted into the rear plate;

[0120] Tensioners 4 are provided on the outside of the front and rear panels, and the two frames are connected by the limiting of the rear and front panels.

[0121] To provide a pressing driving force while avoiding long-term friction, the drive wheel 13 includes: a hub 131 for supporting connection, an inner tube 132 for pressure buffer support, and an outer tire 133 for friction driving. The inner tube 132 is disposed around the outer circumference of the hub 131, and the outer tire 133 is wrapped around the outer wall of the inner tube 132. The outer tire 133 contacts and drives the monorail.

[0122] The outer wall of tire 133 has a smooth, rounded transition bulge in the middle. Under a certain air compression, a flat surface has a larger contact area and therefore less deformation. The smooth, rounded transition bulge, because only the bulge is in contact, can produce a larger deformation, clamping more tightly and better adapting to the tolerances of monorails. In other words, it can clamp the monorail whether it is thin or thick.

[0123] To facilitate the use of local materials and ensure timely pressure supply, the inner tube 132 is made of TPU (resistant to hydraulic oil corrosion), and hydraulic oil is injected inside the inner tube 132.

[0124] To improve braking effect and ensure braking function, the braking device 14 includes: a brake plate 141 that provides lever braking force; a hydraulic cylinder 142 that provides pressure to ensure the braking device 14 is in a non-braking state (or, alternatively, in a braking state); and a brake element 143 that interacts with the monorail to satisfy the braking function. The brake plate 141 is hinged to the outer wall of the frame 111, and the lower end of the brake plate 141 is driven and connected by the hydraulic cylinder 142. The upper end of the brake plate 141 is hinged to the brake element 143, and the other end of the brake element 143 contacts the frame 111 and the monorail for braking.

[0125] Four braking devices 14 are provided, respectively located on both sides of the frame 111.

[0126] The brake plate 141 is arc-shaped (to ensure that the structure is more in line with structural mechanics after the two ends are supported, and to ensure the strength of the brake plate 141). A brake hole 144 is provided at the upper end of the brake plate 141, a drive hole 145 is provided at the lower end of the brake plate 141, and a hinge hole 146 is provided on the lower side of the brake hole 144. The distance between the hinge hole 146 and the brake hole 144 is greater than the distance between the hinge hole 146 and the drive hole 145.

[0127] The two brake plates 141 on the same side of the two frame bodies 111 are connected by a hydraulic cylinder 142. A brake spring 147 is sleeved on the outer wall of the hydraulic cylinder 142 to push the brake plates 141 to rotate outward. When the hydraulic cylinder 142 is working, it constrains the brake spring 147, causing the brake element 143 to disengage from the monorail and achieve a non-braking state. When the brake spring 147 provides braking force, the lever arm on the side of the drive hole 145 is longer, forming a lever effect to provide greater braking force.

[0128] During braking, the brake plate 141 undergoes a rotational motion. Since the hydraulic cylinder 142 is in a free state at the drive hole 145 and can move up and down, there is no interference. However, the brake component cannot move up and down relative to the frame 111. To avoid interference, the brake hole 144 is an elongated hole, allowing the brake component 143 to move along the elongated hole 144 within a certain arc range, thus avoiding interference. Furthermore, to minimize the movement along the length of the elongated hole 144, the brake hole 144, the hinge hole 146, and the drive hole 145 are on the same straight line; that is, the brake plate 141 moves first in the tangential direction, preventing excessive movement along the length of the elongated hole 144, which could lead to delayed braking or friction failure. To meet the braking requirements, the brake component 143 includes: a brake lever 1431 for driving braking and a brake head 1432 for friction braking with the monorail. A telescopic hole is provided through the frame 111, and the brake lever 1431 passes through the frame 111 along the telescopic hole. The brake head 1432 is fixedly connected to one side of the brake lever 1431 passing through the frame 111. In order to improve the braking friction, a rubber friction pad is fixedly connected to the end of the brake head 1432.

[0129] To enhance the limiting effect on the brake lever 1431, a guide body 114 is fixedly connected to the outer wall of the telescopic hole, with the telescopic hole penetrating through the guide body 114. This avoids the defect of insufficient constraint on the brake lever 1431 during braking, which would lead to poor braking performance. The guide body 114 includes: a guide post 1141 for transporting the brake lever 1431 and a connecting wall 1142 for increasing the connection strength of the guide post 1141. The telescopic hole penetrates the center of the guide post 1141, and the connecting wall 1142 is integrally formed on the lower side of the guide post 1141. The guide post 1141 and the connecting wall 1142 are fixedly connected to the frame 111. A hinge hole is provided on the side of the connecting wall 1142 away from the frame 111, allowing it to hinge with the brake hole 144 of the brake plate 141.

[0130] like Figure 1 , Figure 13 and Figure 14 As shown, pulley devices 5 are provided on the upper side of both the lifting arm 2 and the sliding device 1. The pulley devices 5 are slidably hung on the monorail crane 01 to provide suspension force for the entire beam lifting machine.

[0131] The pulley device 5 includes: a connecting frame 51 for connection and fixation, a pulley body 52 that is directly attached to the monorail and supports it, and a buffer support device 53 for supporting and buffering the monorail. The pulley body 52 is connected to the upper side of the connecting frame 51, and the pulley body 52 is slidably connected to the monorail, rolling along the monorail. The buffer support device 53 is provided below the pulley body 52. ​​Through the support of the buffer support device 53, the relative position between the sliding device 1 and the monorail can be stabilized during impacts or severe vibrations, ensuring the stability of the sliding device 1.

[0132] To facilitate the connection between the connecting frame 51 and the monorail, as well as the connection between the connecting frame 51 and the lifting arm 2, the connecting frame 51 includes: an upper frame 511 for connecting with the monorail; and a lower frame 512 for connecting with the lifting arm 2. The lower frame 512 is fixedly connected to the lower end of the upper frame 511, and the upper frame 511 connects to the pulley body 52 and the buffer support device 53.

[0133] To accommodate the I-beam structure of the monorail crane and facilitate the mounting of the pulley body 52 on both sides of the monorail crane, the upper frame 511 includes a left wall 5111, a right wall 5112, and a base 5113. The left and right sides of the base 5113 are fixedly connected to the left wall 5111 and the right wall 5112, respectively, forming a V-shaped structure. The base 5113 is fixedly connected to the lower frame 512.

[0134] The pulley body 52 includes: a pulley 521 for hanging, a pulley rod 522 for fixing the pulley 521, a friction-reducing pad 523 for supporting the pulley 521 and reducing friction between the pulley and the upper frame 511, and a fixing bolt 524 for connecting to the upper frame 511 and fixing the position of the pulley 521. Mounting holes are respectively opened through the left wall 5111 and the right wall 5112 of the frame. The pulley rod 522 passes through the mounting holes and connects to the pulley 521 inside the V-shaped structure. A friction-reducing pad 523 is provided between the pulley 521 and the left wall 5111 or the right wall 5112 of the frame. The pulley rod 522 is fixed outside the V-shaped structure by the fixing bolt 524. First, the diameter of the friction-reducing pad 523 is smaller than that of the pulley; second, the diameter of the friction-reducing pad 523 is larger than the diameter of the mounting hole. This ensures that the friction-reducing pad supports the pulley 521 and avoids friction between the pulley and the upper frame 511 during rotation. The friction-reducing pad first ensures the position of the pulley, and secondly reduces the friction area. Furthermore, by coating the surface of the friction-reducing pad with a friction-reducing material, the smoothness of the pulley's rolling is further improved. Of course, to adapt to the I-shaped monorail structure, the pulleys 521 connected to the left wall 5111 and right wall 5112 of the frame are arranged opposite each other, clamping the monorail between the two pulleys 521 to ensure the stability of the pulley device 5.

[0135] To ensure the tight connection between the pulley device 5 and the monorail during impacts or severe vibrations, and to prevent the lack of a buffer structure from causing damage to the pulley device 5 or the monorail in the event of an impact, thus avoiding safety accidents.

[0136] The buffer support device 53 includes: a support wheel 531 that contacts and supports the bottom of the monorail, a support rod 532 that connects to the support wheel 531, a buffer spring 533 that supports the support rod 532 and improves the buffering effect, a deformation pad 534 that limits the position of the support rod 532 and allows it to slide in a set direction, and a limiting bolt 535 that provides a fixing and clamping effect. To improve the buffering effect, ensure the sliding direction of the support rod, and maintain the connection between the support rod and the buffer spring 533, square support holes are provided at the bottom of the left wall 5111 and the right wall 5112 of the frame. The support rod 532 is also square in structure and is fitted into the support hole for limiting connection. The height of the support hole is greater than the height of the support rod 532, allowing the support rod 532 to slide in the height direction. The square structure of the support rod 532 further avoids the problem of not being able to connect with the buffer spring during rotation. One end of the support rod 532, which extends into the V-shaped structure, is connected to the support wheel 531, which supports the monorail.

[0137] In order to limit and fix the entire buffer support device 53, a deformation pad 534 and a limiting bolt 535 are connected to one end of the support rod 532 that extends out of the outer wall of the frame base 5113.

[0138] Specifically, multiple deformation pads 534 are provided, and the surface of each deformation pad 534 is coated with graphite to increase the friction between them. The opening diameter of each deformation pad 534 is larger than the maximum size of the support rod 532, but smaller than the minimum outer diameter of the limiting bolt 535. This ensures that the limiting bolt 535 is limited while allowing the support rod to move within a certain space. This guarantees the buffer space of the entire buffer support device and improves the buffering effect.

[0139] To ensure the deformation length of the buffer spring 533 and to provide a certain constraint on it, a spring hole 536 is provided at the bottom of the support hole. The buffer spring 533 is connected inside the spring hole 536, with its upper end extending out of the spring hole 536 and fixedly connected to the bottom of the support rod 532. During compression deformation, the buffer spring 533 can retract into the spring hole 536, avoiding occupying the size of the support hole. Furthermore, during deformation, once the buffer spring 533 is fully compressed into the spring hole, no further force can be applied to it, ensuring its protective function and preventing damage to the buffer spring 533 due to excessive force during severe vibration.

[0140] To ensure the support effect of the support rod 532 and prevent tilting, which would compromise the cushioning support effect of the support wheel 531, at least two spring holes 536 are arranged side by side, with one spring hole 536 at each end of the support hole; preferably, multiple spring holes 536 are arranged side by side, which not only increases the support force but also ensures the balance of the support.

[0141] Due to the harsh working environment and high coal dust levels in underground coal mines, dust easily accumulates inside the spring holes 536, affecting the performance of the buffer springs. Therefore, to prevent dust accumulation, a drain hole 537 is provided at the lower end of each spring hole 536, with the other end of the drain hole 537 extending out of the frame base 5113; the accumulated dust can be discharged through the drain hole 537. To lubricate the support wheels 531 and reduce friction between the support wheels 531 and the monorail, a lubricating oil cavity 513 is provided on the upper side of the middle of the frame base 5113, with the lower side of the support wheels 531 extending into the lubricating oil cavity 513; by injecting lubricating oil into the lubricating oil cavity 513, the support wheels 531 are lubricated. Furthermore, the lubricating oil carried by the rotating support wheels 531 flows into the spring holes along the support holes, not only lubricating the buffer springs but also causing dirt inside the spring holes 536 to flow out through the drain holes, preventing dust accumulation. Of course, to avoid excessive lubricating oil flowing into the support holes, the upper surface of the lubricating oil cavity 513 is lower than the end of the support hole. This ensures that only a portion of the lubricating oil carried by the rotation of the support wheel 531 enters the support hole.

[0142] To ensure both cushioning and connection strength, the support wheel 531 includes: a rigid support body 5311 primarily providing connection and fixation; a rigid rotating body 5312 that rotates relative to the rigid support body 5311; and a flexible sliding body 5313 providing cushioning and support for the monorail. The rigid support body 5311 is fixedly connected to the end of the support rod 532. The rigid rotating body 5312 is rotatably sleeved on the outer wall of the rigid support body 5311, and the flexible sliding body 5313 is fixedly connected to the outer wall of the rigid rotating body 5312.

[0143] To improve the fit between the flexible sliding body 5313 and the monorail, the outer wall of the flexible sliding body 5313 is adapted to the bottom of the monorail.

[0144] Specifically, the bottom surface of the monorail is shaped like a portal frame, with the flexible sliding body 5313 supported inside the portal frame. The two side walls of the monorail limit the movement of the flexible sliding body 5313. Since there are two opposing buffer support devices 53, they can limit the lateral position of the monorail. Furthermore, the flexible sliding body 5313 is made of a flexible material, thus buffering and reducing lateral vibrations of the monorail.

[0145] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
