Description

Technical Field

[0001] The utility model relates to the technical field of hoisting devices, in particular to a hoisting device suitable for mine electromechanical equipment. Background Art

[0002] Mining electromechanical equipment refers to the mechanical equipment required for mining, mineral processing, and prospecting operations, such as conveyors, ventilators, drainage pumps, crushers, etc. When installing and unloading such mechanical equipment on the construction platform, a lifting device is generally required to assist in handling. The most common lifting device is to install an electric hoist on a gantry, use the wire rope on the electric hoist to lift the electromechanical equipment, and then the gantry will move the electromechanical equipment to the designated workstation.

[0003] Most hoisting devices are mainly used for hoisting from directly above the mine electromechanical equipment. When encountering equipment with longer lengths, such as conveyors and ventilators, their center of gravity may not be at the geometric center of the equipment. Hoisting the equipment directly above the equipment may cause it to tilt or shake due to the shift in center of gravity, making it difficult to maintain balance. In addition, during the hoisting and installation of mine electromechanical equipment, in order to meet the specific angle required for equipment installation and to correctly connect with other equipment or structures in the mine, the equipment needs to be hoisted to a specified tilt angle. However, most hoisting devices are not easy to hoist the equipment at the specified tilt angle. Utility Model Content

[0004] The purpose of the utility model is to provide a hoisting device suitable for mine electromechanical equipment to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A hoisting device suitable for mine electromechanical equipment includes a gantry, the gantry including two support columns, movable columns slidably mounted on top of the support columns, a crossbeam fixed between the tops of the two movable columns, and further comprising:

[0007] There are two suspension assemblies, both of which are slidably connected to the crossbeam. The suspension assemblies include an electric hoist, a first steel wire rope is rotatably wound around the reel of the electric hoist, a second steel wire rope is slidably connected to the bottom of the first steel wire rope, and hooks are installed at both ends of the second steel wire rope, and the hooks can be connected and fixed to the suspension rings on the mining electromechanical equipment;

[0008] A telescopic component is fixed between the two suspension components and is capable of adjusting the distance between the two suspension components;

[0009] There are two reduction motors, both of which are fixed to the movable column. A steel wire rope is fixed between the output end of the reduction motor and the electric hoist at the corresponding position.

[0010] The positioning component is arranged between two suspension components and can make the suspension components statically suspend the mining electromechanical equipment.

[0011] Furthermore, a traction wheel fixedly wound with the third steel wire rope is fixed to the output end of the reduction motor, and the third steel wire rope penetrates through the movable column.

[0012] Furthermore, two connecting seats are fixed to the top of the electric hoist, and two rollers that are both rollingly connected to the crossbeam are rotatably connected inside the connecting seats.

[0013] Furthermore, a U-shaped block is fixed between the two connecting seats, and the U-shaped block is slidably abutted against the crossbeam.

[0014] Furthermore, the telescopic component includes a square pipe, one end of the square pipe is slidably connected with a sliding rod, and the square pipe and the sliding rod are respectively fixedly connected to the U-shaped blocks at the corresponding positions.

[0015] Furthermore, the positioning component includes:

[0016] A positioning column fixedly connected to the crossbeam, and a plurality of circular holes are formed through the outer side of the positioning column;

[0017] Two shaft rods are inserted between the movable column and the positioning column to fix the position of the first steel wire rope.

[0018] Furthermore, a first ring that is movably inserted into the shaft rod is fixed to the bottom end of the first steel wire rope, and a second ring sleeved with the first ring is fixed to the top end of the second steel wire rope.

[0019] Compared with the prior art, the beneficial effects of the present utility model are:

[0020] By installing two electric hoists on the crossbeam of the gantry, when encountering equipment with relatively large length dimensions such as conveyors and ventilators, the two electric hoists can move in opposite directions, and the two electric hoists are respectively arranged at both ends of the equipment. The bottom end of the first steel wire rope on the electric hoist is penetrated by the second steel wire rope, and hooks are fixedly installed at both ends of the second steel wire rope. The second steel wire rope can move on the first steel wire rope to adjust the distance from both ends of the second steel wire rope to the suspension ring of the equipment. Even if the heights of two adjacent suspension rings on the equipment are different, the first steel wire rope can still pass through the middle of the second steel wire rope to hoist the equipment, and the two electric hoists hoist the equipment from both ends of the equipment respectively, which is beneficial to improving the stability of equipment hoisting.

[0021] By arranging two suspension components at both ends of the device respectively, when two electric hoists simultaneously wind the wire rope 1 of the same length, the device can be hoisted vertically upwards. When the device needs to be adjusted to an inclined installation state during the hoisting and installation process, one of the electric hoists can release the wire rope 1, and the other electric hoist winds the wire rope 1, so that the suspended device can tilt towards the direction where the wire rope 1 is released. The greater the lengths of the two wire ropes 1 wound and released respectively, the greater the installation inclination angle of the device adjusted, thus realizing flexible adjustment of the installation angle of the device.

Detailed Embodiment

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] Embodiment 1, please refer to Figure 1 - Figure 4In an embodiment of the present invention, a hoisting device suitable for mine electromechanical equipment includes a gantry 100, wherein the gantry 100 includes two support columns 110, and a movable column 111 is fixedly installed on the top of the support column 110. A crossbeam 120 is fixedly connected between the tops of the two movable columns 111. Two suspension assemblies 200 are installed on the outside of the crossbeam 120. The suspension assembly 200 includes an electric hoist 210 that is rollingly connected to the crossbeam 120. A steel wire rope is rotatably wound on the reel of the electric hoist 210. One 220, the bottom of the wire rope one 220 is slidably sleeved with a wire rope two 230, and both ends of the wire rope two 230 are installed with hooks 231 for suspending mining electromechanical equipment, and a telescopic component 300 is installed and fixed between the two suspension components 200. The top outer side of the movable column 111 is fixedly connected with a reduction motor 400, and a wire rope three 410 is fixed between the output end of the reduction motor 400 and the electric hoist 210 at the corresponding position. The wire rope three 410 is used to pull the electric hoist 210 to move its position.

[0029] Specifically, two electric hoists 210 are rollingly installed on the crossbeam 120 of the gantry 100. When the axial length of the hoisted mining electromechanical equipment is long, the two electric hoists 210 can be moved to the upper positions of the two ends of the equipment respectively, and then the equipment can be hoisted from both ends of the equipment at the same time with the help of wire rope 1 220 and wire rope 2 230. Compared with using a single wire rope to hoist from the middle of the equipment, it is beneficial to improve the stability of the equipment hoisting. When the equipment is hoisted to the installation position and needs to be installed at an inclined angle, the two electric hoists 210 can be respectively reeled and pulled on the wire rope 1 220 on their respective reeling wheels, so that the equipment is gradually tilted to the specified installation angle, so that the hoisting device can not only stabilize the hoisting equipment but also assist in adjusting the installation inclination angle of the equipment.

[0030] like Figure 1 and Figure 2 As shown, in this embodiment, a bottom beam 130 is fixed to the bottom of the support column 110 of the gantry 100, and movable wheels are installed and fixed at both ends of the bottom of the bottom beam 130. The movable wheels facilitate the overall movement of the gantry 100, wherein the movable column 111 can be moved up and down inside the support column 110 to adjust its position and be fixed. The movable column 111 can be adjusted up and down inside the support column 110 by a manual hydraulic cylinder or other telescopic equipment. The above-mentioned gantry 100 is a prior art, and the specific structural content of the gantry 100 will not be described in detail.

[0031] like Figure 3As shown, in this embodiment, a traction wheel wound and fixed with the third wire rope 410 is fixed to the output end of the reduction motor 400. The third wire rope 410 passes through the movable column 111. When it is necessary to pre-adjust the distance between the two electric hoists 210 to meet the requirement of hoisting equipment with a larger axial length, the user first removes the fixing bolts on the telescopic assembly 300, and then makes the reduction motor 400 drive the traction wheel to rotate and wind up the third wire rope 410, so that the two electric hoists 210 move in opposite directions. When the distance between the two electric hoists 210 is adjusted, the position of the telescopic assembly 300 after elongation can be fixed again with bolts.

[0032] As Figure 3 and Figure 4 As shown, in this embodiment, two connecting seats 240 are fixed to the top of the electric hoist 210. Two rollers 241 that are both rotatably connected to the inside of the connecting seat 240 and rollingly connected to the cross beam 120 are provided. When the electric hoist 210 moves on the cross beam 120, the rollers 241 roll along the cross beam 120, which facilitates the stable movement of the electric hoist 210 on the cross beam 120.

[0033] In this embodiment, a U-shaped block 242 is fixed between the two connecting seats 240. The U-shaped block 242 is slidably abutted against the cross beam 120. The U-shaped block 242 is mainly used to install and fix the telescopic assembly 300 and the two electric hoists 210 together. When the two reduction motors 400 keep the tendency of rotating and winding up the third wire rope 410 when the telescopic assembly 300 is fixed and cannot be extended, the electric hoist 210 can be stably fixed at the top of the cross beam 120, effectively preventing the electric hoist 210 from moving by itself.

[0034] As Figure 4 As shown, in this embodiment, the telescopic assembly 300 includes a square tube 310. A slide bar 320 is slidably connected to one end of the square tube 310. The square tube 310 and the slide bar 320 are respectively fixedly connected to the U-shaped block 242 at the corresponding positions. A plurality of bolt holes are formed through the outer sides of the square tube 310 and the slide bar 320.

[0035] In this embodiment, when it is necessary to adjust the distance between the two electric hoists 210, the bolts inserted between the slide bar 320 and the square tube 310 are removed in advance. At this time, the slide bar 320 and the square tube 310 can slide relative to each other, so as to realize the adjustment of the distance between the two electric hoists 210. When the distance between the two electric hoists 210 is adjusted, the bolts can be inserted and fixed into the corresponding bolt holes between the slide bar 320 and the square tube 310 to be locked, so as to fix the length of the telescopic assembly 300. In addition, when disassembling or installing the bolts, the height of the entire gantry 100 can be reduced, which is convenient for the user to disassemble or install the bolts.

[0036] As Figure 4As shown, in this embodiment, the opening position of the hook 231 is hinged with a pin block 2311, and a torsion spring is installed between the pin block 2311 and the rotating position of the hook 231, so that the pin block 2311 can prevent the suspension ring on the mining electromechanical equipment from detaching from the hook 231 by itself. When there are multiple suspension rings at the end of the equipment, multiple wire ropes 230 can be appropriately passed through the circular ring 232, and each wire rope 230 can pass through the two suspension ring points on the pulling equipment through the circular ring 232.

[0037] Example 2. Based on Example 1, during the hoisting and installation process of mine electromechanical equipment, it is sometimes necessary to wait for other equipment to be in place or operators to be in place before installation. At this time, the electromechanical equipment will be suspended in the air and stationary. The brake of the electric hoist 210 needs to continue to work when the equipment is suspended and stationary to prevent the equipment from moving downward. The continuous braking state will cause the friction plate and other components of the brake to wear more severely. In order to achieve the electric hoist 210 being able to stop working when the electromechanical equipment is suspended and stationary.

[0038] like Figure 3 As shown, in this embodiment, the positioning assembly 500 includes a positioning column 510 fixedly connected to the beam 120, and a plurality of circular holes 520 are opened on the outer side of the positioning column 510. A shaft rod 530 is movably inserted between the movable column 111 and the circular hole 520 of the positioning column 510. The shaft rod 530 is used to fix the position of the wire rope 220, and the bottom end of the wire rope 220 is fixed with a ring 221 movably inserted with the shaft rod 530.

[0039] In this embodiment, after the ring 121 on the wire rope 120 is hoisted to the outside of the positioning column 510, the shaft 530 can be used to insert it from the socket 1111 on the outside of the movable column 111, so that one end of the shaft 530 passes through the ring 121 and is then inserted into the circular hole 520 of the positioning column 510. Then the electric hoist 210 can release the wire rope 120. At this time, the weight of the equipment pulled upward by the wire rope 230 is applied to the shaft 530. The shaft 530 is directly fixed between the gantry 100 and the positioning column 510, eliminating the need to continue using the electric hoist 210 to suspend the mining electromechanical equipment for a long time, and effectively preventing the wire rope 1220 from pulling the electric hoist 210 downward at all times when it is suspended in a static state.

[0040] In this embodiment, a plurality of circular holes 520 and insertion holes 1111 are respectively provided at corresponding heights on the positioning column 510 and the movable column 111, so that the shaft rod 530 can adapt to the circular ring 1 221 and be inserted into the fixed circular ring 1 221 at different positions, wherein the diameter of the circular ring 1 221 is larger than the diameter of the shaft rod 530, so that the shaft rod 530 can be easily inserted into the interior of the circular ring 1 221.

[0041] In this embodiment, combined with Figure 4The top of the wire rope 230 is fixed with a ring 232 that is sleeved with the ring 1 221. The ring 1 221 and the ring 2 232 are arranged at right angles, so that the wire rope 1 220 is connected and fixed to the ring 1 221 through the shaft 530 without being interfered with by the lifting direction of the wire rope 230.

[0042] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
