Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of door and window conveying, in particular to a high-stability safe conveying equipment for conveying aluminum alloy door and window and stairs. BACKGROUND

[0002] Aluminum alloy door and window refers to door and window with aluminum alloy as the main structural material. Aluminum alloy is a kind of light and high-strength metal material composed of pure aluminum and other elements (such as copper, manganese, magnesium, silicon, etc.). The density of aluminum alloy is low, but the strength is high, so the door and window is light and durable.

[0003] At present, with the decoration or improvement of people's houses, many old buildings or low-rise buildings may not be equipped with elevators, so building materials such as aluminum alloy door and window need to be carried to the designated floor by stairs. In some construction sites, due to space limitation or construction safety consideration, some elevators cannot be used to carry aluminum alloy door and window for people, so workers need to carry aluminum alloy door and window from stairs to the designated floor, which causes low overall carrying efficiency and increases the labor intensity of workers.

[0004] In the prior art, workers can only carry from the stairs, in order to reduce the labor intensity of workers carrying, there is a device to help workers carry aluminum alloy door and window from the stairs, specifically, Chinese patent publication No. CN113371387B adopts a cross-shaped carrying frame to clamp and fix the aluminum alloy door and window, a rubber pad can be provided with a waistband tied around the waist, and a U-shaped plate slides on the stair handrail, so that when the carrying worker holds the device to go upstairs, the body will push the push rod to make the whole device rise along the stair handrail, reducing the carrying difficulty of the worker, not only can achieve the effect of single-person carrying, but also can solve the problem of collision between aluminum alloy door and window and the ground.

[0005] However, careful study of the above-mentioned scheme shows that the scheme still has some deficiencies, specifically, the U-shaped plate and the trapezoidal clamping block are used to adhere to the stair handrail for sliding, although it can reduce the labor intensity of workers carrying, but the stair is designed in multiple levels and staggered, when the U-shaped plate moves to the corner of the stair, the trapezoidal clamping block needs to be adjusted manually, which causes difficulty in reversing the U-shaped plate, wastes a lot of time, and cannot smoothly turn to the other handrail, resulting in low efficiency of workers carrying aluminum alloy door and window, and the sliding process also easily causes damage to the handrail, such as scratches and cracks on the surface of the handrail.

[0006] Therefore, when workers carry aluminum alloy door and window on the stairs, the present application aims to improve the efficiency of workers carrying aluminum alloy door and window by using the handrail at the corner, and reduce the damage to the surface of the handrail. SUMMARY

[0007] The main objective of this invention is to provide a highly stable and safe conveying device for transporting aluminum alloy doors and windows via stairs, which aims to improve the efficiency of workers moving aluminum alloy doors and windows with the help of handrails when turning corners, while reducing the problem of damage to the handrail surface.

[0008] To achieve the above objectives, the present invention proposes a highly stable and safe conveying device for conveying aluminum alloy doors, windows, and stairs, comprising:

[0009] The casing is open on one side;

[0010] Support members, installed on the side of the housing away from the open, are used to clamp and support doors and windows;

[0011] A pair of side rollers are disposed on the open side of the housing. Each side roller includes at least one guide roller that can fit against the side of the armrest, a drive gear fixed to the top of the guide roller, and a connecting gear that meshes with the drive gear. A U-shaped frame is rotatably provided on the opposite side of the two connecting gears.

[0012] A main frame, disposed between a pair of side rollers, wherein a guide shaft is provided on the side of the U-shaped frame facing the main frame, and the guide shaft is slidably connected to the main frame; and

[0013] A thrust connector, rotatably connected to the top of the housing, is used to connect an auxiliary rod and facilitates the application of force at an angle.

[0014] Furthermore, when each of the side rollers is provided with two guide rollers, a connecting piece is provided between the center of the drive gear and the connecting gear.

[0015] Furthermore, an elastic element is provided between the guide shafts located on both sides of the main frame.

[0016] Furthermore, the inner wall of the main frame is provided with a guide plate sleeved on the outside of the elastic member.

[0017] Furthermore, the U-shaped frame is provided with an extrusion member at one end near the main frame, and a cam is fixedly installed at one end of the thrust joint that passes through the housing. The cam fits against the outer wall of the extrusion member to adjust the distance between the U-shaped frame and the main frame.

[0018] Furthermore, both ends of the main frame are provided with load-bearing components. The load-bearing components include a mounting plate that can be detachably fixed to the main frame, a load-bearing frame fixed to the bottom end of the mounting plate, and a guide wheel that is rotatably provided at the bottom end of the load-bearing frame. The guide wheel is used to fit the staircase.

[0019] Furthermore, the support frame is provided with load blocks on both sides away from the guide wheel, and the load blocks are engaged with the main frame.

[0020] Furthermore, the mounting plate, the support frame, and the guide wheel are integrally formed.

[0021] Furthermore, the main frame is provided with an end platform at one end near the bearing member, the end platform being used to reserve an area for the installation of the guide wheel.

[0022] Furthermore, the U-shaped frame is provided with a ratchet device on the side facing the connecting gear to restrict the connecting gear from reversing.

[0023] The above technical solution has the following advantages:

[0024] This invention uses a thrust joint to install an auxiliary rod, making it convenient for workers to apply force. The support is placed on the aluminum alloy doors and windows, and the side rollers are distributed on both sides of the main frame, allowing the side rollers to press against the sides of the handrail. At the same time, the side rollers can move towards both sides of the escalator. When the conveying device moves upward, the guide rollers can move with the bends of the escalator, thereby increasing the movement space between the guide rollers and the handrail at the bends, ensuring that the conveying device can pass smoothly. The entire process does not require manual handling or large-scale adjustments, reducing the labor intensity of workers, improving the efficiency of workers in moving aluminum alloy doors and windows with the help of the handrail when turning corners, and reducing the problem of damage to the handrail surface.

[0025] Elastic elements are provided between the guide shafts on both sides of the main frame. The elastic elements are used to pull the guide shafts at both ends. At the same time, an extrusion element is provided at the end of the U-shaped frame near the main frame. A cam is fixedly installed at the end of the thrust joint that passes through the shell. The cam fits against the outer wall of the extrusion element. The worker ensures the thrust for translation, which automatically drives the cam to rotate. The rotation of the cam causes the extrusion element on the side closest to itself to automatically unfold without manual adjustment. Attached Figure Description

[0037] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the following specific embodiments are only used to explain the invention and do not constitute a limitation thereof.

[0038] like Figures 1 to 3 As shown, a highly stable and safe conveying device for conveying aluminum alloy doors, windows, and stairs includes a housing 1, a support member, a pair of side rollers 2, a main frame 7, and a thrust connector 3. One side of the housing 1 is open. The support member is installed on the side of the housing 1 away from the open side to clamp and support the doors and windows. The pair of side rollers 2 are located on the open side of the housing 1. Each side roller 2 includes at least one guide roller 21 that can fit against the side of the handrail, a drive gear 22 fixed to the top of the guide roller 21, and a connecting gear 23 that meshes with the drive gear 22. A U-shaped frame 24 is rotatably provided on the opposite side of the two connecting gears 23. The main frame 7 is located between the pair of side rollers 2 and is fixed to the housing 1, such as by bolting or plugging. A guide shaft 75 is provided on the side of the U-shaped frame 24 facing the main frame 7, and the guide shaft 75 is slidably connected to the main frame 7. The thrust connector 3 is rotatably connected to the top of the housing 1 to connect an auxiliary rod and to facilitate the application of tilting force. The conveying equipment is divided into two directions: one is the upward direction along the stairs, and the other is the unfolding direction perpendicular to the escalator. The housing 1 has a through groove along the upward direction so that the two sides of the housing 1 along the unfolding direction can cover the two sides of the escalator. The housing 1 also has an observation groove in the unfolding direction to facilitate the observation of the specific condition of the side roller 2. The support can clamp the aluminum alloy doors and windows, and after being clamped by the support, it can be moved upward with the housing 1 to realize the handling operation, reducing the burden on the workers.

[0039] like Figure 1 As shown, specifically, the support can be a lever support or a frame support fixed to the outer periphery of the thrust joint 3. For example, aluminum alloy doors and windows can be hoisted using ropes, and support points can be set at the edge of the shell 1. In this application, the support includes a support base 4, a support rod 5, and a clamping member 6. The support base 4 is fixed to the top of the shell 1, at least two of which are provided and symmetrically arranged along the unfolding direction. One end of the support rod 5 is rotatably mounted on the support base 4, and the other end is fixed to the clamping member 6. The middle part of the support base 4 rests on at least one support base 4 to provide support. The clamping member 6... Used for clamping aluminum alloy doors and windows. Since most aluminum alloy doors and windows are square, threaded clamping is used. Cross clamps, hydraulic clamps, tilting transport plates, or other forms can also be used. If cross clamps are used, they clamp the aluminum alloy doors and windows from all four sides to maintain overall stability. Hydraulic clamps can be cross-shaped or can clamp only the two sides of the aluminum alloy doors and windows. If tilting transport plates are used, the transport plate is tilted to the housing 1 so that the aluminum alloy doors and windows are inserted into the transport plate from the worker's side. The tilted transport plate can effectively prevent the aluminum alloy doors and windows from shifting or falling, and also facilitates picking and putting them in during transportation.

[0040] like Figures 1 to 3 As shown, in one embodiment of this application, the side roller 2 can be two guide rollers 21 attached to the side of the handrail, or only a single guide roller 21 attached to the side of the handrail. When a single guide roller 21 is used on both sides, the drive gear 22 and the connecting gear 23 are distributed along the unfolding direction, and only two guide rollers 21 are attached to both sides of the handrail respectively, thereby achieving stable transmission on the side. If a single guide roller 21 is used on one side of the handrail and two guide rollers 21 are used on the other side, the single guide roller 21 is located on the plane between the two guide rollers 21, and can also achieve transmission with the handrail. Preferably, the single guide roller 21 is snapped onto the handrail. In the inward direction; if two guide rollers 21 are provided on both sides of the handrail, and a connecting piece 27 is provided between the center of the drive gear 22 and the connecting gear 23, the connecting piece 27 is used to connect the drive gear 22 and the connecting gear 23, ensuring that the drive gear 22 surrounds the center of the connecting gear 23. The guide rollers 21 on each side are respectively attached to the side of the handrail, thereby ensuring the stable transmission of the conveying device. Since the drive gear 22 and the connecting gear 23 mesh with each other, when the guide rollers 21 are squeezed by the handrail, they can rotate along the center of the connecting gear 23, thereby avoiding the corners of the escalator and satisfying the process of the conveying device moving up the escalator.

[0041] like Figure 1As shown, in one embodiment of this application, the thrust connector 3 is a connector installed at the top of the housing 1. The thrust connector 3 can be directly connected to the auxiliary rod. Specifically, it can be threaded to the auxiliary rod, or it can be fixed by a pin or snap-fit. The auxiliary rod can be rotated to adjust its position. The auxiliary rod is then placed against the worker's abdomen or chest by a strap or rubber sleeve, thereby driving the housing 1 forward in the upward direction, which greatly reduces the labor intensity of the worker.

[0042] like Figure 4 and Figure 5 As shown, in one embodiment of this application, an elastic element 74 is provided between the guide shafts 75 on both sides of the main frame 7. The elastic element 74 is used to pull the guide shafts 75 at both ends, and the guide shafts 75 are slidably connected to the main frame 7, causing the side rollers 2 on both sides to move towards the main frame 7, thereby generating a lateral force to clamp the escalator and maintain the clamping degree and movement flexibility of the side rollers 2 on the handrail. It should be noted that the elastic element 74 is preferably a spring to ensure the elastic force between the two elastic elements 74. Elastic bands or leaf springs can also be used instead, and the specific configuration can be customized according to the needs.

[0043] like Figure 4 and Figure 5 As shown, the inner wall of the main frame 7 is provided with a guide plate 72 sleeved on the outside of the elastic member 74. The guide plate 72 is used to guide the outer wall of the elastic member 74, which can greatly increase the contact area between the guide shaft 75 and the main frame 7, ensure the stability of the sliding of the guide shaft 75, and also improve the structural strength of the movement of the guide shaft 75. When the elastic member 74 is a spring, straight grooves need to be machined on both sides of the guide plate 72 to prevent the end hook of the spring from blocking the inner wall of the guide plate 72, which would interfere with the sliding of the guide shaft 75 on the inner wall of the guide plate 72, affect the range of movement, and also squeeze the end hook of the spring, causing damage to the spring. The inner bottom wall of the main frame 7 is also fixedly installed with a column 73. The column 73 can be fixed only to the main frame 7, or it can be fixed to the guide plate 72 installed on the inner wall of the main frame 7, which increases the force on the column 73 in the horizontal direction and also improves the structural strength of the guide plate 72 and the column 73.

[0044] like Figure 1 , Figure 2 and Figures 4 to 6As shown in one embodiment of this application, the U-shaped frame 24 is provided with an extrusion member 32 at one end near the main frame 7. A cam 31 is fixedly installed at one end of the thrust connector 3 that penetrates the housing 1. The cam 31 fits against the outer wall of the extrusion member 32 to adjust the distance between the U-shaped frame 24 and the main frame 7. The top of the column 73 is rotatably connected to the cam 31. When the cam 31 rotates, the protruding part of the cam 31 extrudes the extrusion member 32, causing the extrusion member 32 to gradually move along the unfolding direction, thereby driving the corresponding side roller 2 to unfold. At this time, the elastic member 74 is subjected to tension. This process can increase the range of motion of the guide rollers 21 on both sides of the escalator. When passing through the bend of the escalator, the guide rollers 21 on both sides can unfold more easily, making it easier for the conveying device to pass through the bend of the escalator. After the guide rollers 21 with increased range of motion pass through the bend of the escalator, the cam 31 gradually returns to its original position, and the elastic member 74, through its own... The elastic force causes the guide rollers 21 on both sides to press against the sides of the escalator again, allowing it to move upwards and be transferred again. It should be noted that the rotation of the cam 31 is relatively synchronized with the thrust joint 3. The worker pushes upwards with the auxiliary rod, which tilts upwards and causes the side rollers 2 to move upwards. When the worker passes the corner of the escalator, he will take big steps forward and speed up his pace. He will also cause the thrust joint 3 to rotate through the auxiliary rod, which in turn causes the cam 31 to rotate at a larger angle. The cam 31 will squeeze the squeezing part 32 on one side, preferably squeezing the squeezing part 32 facing the worker, so that the U-shaped frame 24 gradually moves in the unfolding direction, realizing automatic unfolding operation without manual adjustment.

[0045] Specifically, the extrusion part 32 can be integrally formed with the U-shaped frame 24, that is, ribs are provided on the edge of the U-shaped frame 24 to facilitate the extrusion and unfolding of the cam 31. In this application, the extrusion part 32 is preferably a wheel, so that the wheel and the cam 31 have rolling friction to reduce friction. In addition, the extrusion part 32 can also be a long strip or arc block fixed to one end of the U-shaped frame 24 near the cam 31. It should be noted that the cam 31 can be set on both sides of the main frame 7, or it can be set only on one side of the main frame 7. For example, the cam 31 can be split into two parts. The first part is rotatably set on one side of the main frame 7 and is in contact with the extruder 32 on one side. The other part is set on the other side of the main frame 7 and is in contact with the extruder 32 on the other side. This drives the side roller 2 to move back and forth along the unfolding direction. Alternatively, the cam 31 can be rotatably set on both the top and bottom sides of the main frame 7. At least one side of the U-shaped frame 24 can be set with an extruder 32. In this application, it is preferred that the cam 31 is rotatably set on the top of the main frame 7 and the extruders 32 are all set on the top of the U-shaped frame 24. The cam 31 is in contact with both sides of the U-shaped frame 24 at the same time.

[0046] like Figure 6 , Figure 8 and Figure 9As shown, the main frame 7 has a bearing member 76 at both ends. The bearing member 76 includes a mounting plate 761 that can be detachably fixed on the main frame 7, a bearing frame 762 fixed at the bottom of the mounting plate 761, and a guide wheel 763 that is rotatably provided at the bottom of the bearing frame 762. The guide wheel 763 is used to fit the staircase. To improve the load-bearing capacity of the conveying device, guide wheels 763 are installed at both ends of the main frame 7. The guide wheels 763 are in contact with the surface of the escalator to reduce the wear of the escalator and also reduce the resistance in the upward direction of the conveying device. Specifically, the end of the mounting plate 761 near the column 73 is arc-shaped and fits against the outer wall of the column 73. The mounting plate 761 is detachable from the main frame 7 and can be fixed by bolts, plugging, or snapping. In this application, the inner wall of the main frame 7 has a groove for plugging the mounting plate 761. The mounting plate 761 can be pre-fixed by snapping and then fixed to the end of the main frame 7 by bolts. As the mounting plate 761 is fixed, the mounting plate 761 drives the guide wheels 763 to move to the end of the main frame 7 through the bearing frame 762, completing the installation of the guide wheels 763. The overall installation method is simple and does not require separate installation of the guide wheels 763, reducing assembly steps.

[0047] Specifically, the support frame 762 has load blocks 764 on both sides away from the guide wheel 763. The load blocks 764 are engaged with the main frame 7. As the mounting plate 761 is fixed to the main frame 7, the support frame 762 drives the guide wheel 763 to be assembled on the main frame 7. The load blocks 764 are also engaged at the end of the main frame 7. The load blocks 764 are located on the lower side of the main frame 7, so that when the guide wheel 763 contacts the escalator surface, the load blocks 764 can provide sufficient load-bearing capacity, and the load-bearing force of the guide wheel 763 can be fully transferred to the main frame 7. The mounting plate 761 is detachably connected to the mounting plate 762. Because the support frame 762 is symmetrically arranged, its two ends can be bent towards each other or away from each other. It can be fixed with bolts to the mounting plate 761. In this application, it is preferable that the mounting plate 761, the support frame 762 and the guide wheel 763 are integrally formed, which greatly reduces the assembly difficulty, saves production costs, and also improves the structural strength.

[0048] like Figure 2 , Figure 4 , Figure 6 , Figure 8 and Figure 9As shown, in one embodiment of this application, the main frame 7 is provided with an end platform 71 near the bearing member 76. The end platform 71 is used to reserve an installation area for the guide wheel 763. The end platform 71 is bent toward the mounting plate 761. At this time, the carrier block 764 rests against the lower side of the end platform 71, so that the carrier block 764 directly rests against the bottom of the end platform 71. The bearing capacity of the guide wheel 763 can be fully transferred to the end platform 71. The end platform 71 is provided with a groove for inserting the guide wheel 763 to facilitate assembly. The setting of the end platform 71 can increase the distance of the overall main frame 7 to the escalator, maintain the center of gravity of the conveying device, improve the stability of the movement, and at the same time ensure the assembly space of the guide wheel 763.

[0049] like Figure 2 , Figure 3 and Figure 7 As shown in one embodiment of this application, the U-shaped frame 24 is also provided with a ratchet device on the side facing the connecting gear 23 to restrict the reverse rotation of the connecting gear 23. The ratchet device includes a ratchet tooth, which is mounted on the side of the U-shaped frame 24 facing the connecting gear 23. The ratchet is located at the end of the connecting gear 23, making the ratchet device a hidden design and simple to assemble. The ratchet device can be used simply by assembling the U-shaped frame 24 and the connecting gear 23. When the conveyor is on the inclined surface of the escalator, the worker does not apply an upward force. The ratchet device restricts the rotation of the connecting gear 23. After the connecting gear 23 is restricted, the connecting gear 23 and the drive gear 22 no longer rotate, thereby restricting the guide roller 21 from guiding the side of the escalator and preventing the conveyor from slipping down on its own when the worker is resting.

[0050] like Figures 1 to 3As shown, in one embodiment of this application, the housing 1 has straight grooves in the unfolding direction, and a movable block 25 is slidably connected in each straight groove. A positioning shaft 26 is rotatably connected to the end of the U-shaped frame 24 and the axis of the connecting gear 23. One end of the support rod 5 rotates with the support base 4, and the middle part of the support rod 5 can be supported by the movable block 25. The top end of the movable block 25 can be inserted, snapped, or slidably connected to the support rod 5. The end of the movable block 25 facing inwards from the housing 1 is fixed to the positioning shaft 26, specifically by bolt fixing, or the end of the movable block 25 facing inwards from the housing 1 is fixedly connected to the U-shaped frame 24, specifically by welding or bolt fixing. When the side roller 2 faces inwards from the unfolding direction... During movement, the U-shaped frame 24 or the positioning shaft 26 can automatically drive the moving block 25 to move in the unfolding direction, thereby increasing the support force on the clamping member 6 and making the support of the support rod 5 more stable when the conveying device passes through the corner of the escalator. In the above method, the support rod 5 can be a telescopic rod. When the moving block 25 drives the moving part of the support rod 5 to extend outward, the distance between the clamping member 6 and the escalator can be increased, avoiding the aluminum alloy door and window from colliding with the corner of the escalator and improving the safety of the transfer. Since multiple support seats 4 are provided, rubber pads or cardboard can be placed on the support seats 4 so that the support rod 5 can be pressed on the rubber pads or cardboard, which can increase the fulcrum of the support rod 5 and ensure the support capacity.

[0051] In use, the worker first fixes the auxiliary rod to the thrust connector 3, then assembles the aluminum alloy door / window onto the clamping part 6, holds one end of the housing 1, and moves the housing 1 upwards using the auxiliary rod. The guide wheel 763 moves upwards along the surface of the escalator. Simultaneously, the guide roller 21, under the action of the elastic element 74 and the U-shaped frame 24, adheres to the side of the escalator, thus limiting the overall stability of the conveying device. When the worker rests during the upward movement, the ratchet device restricts the rotation of the connecting gear 23, thereby preventing the guide roller 21 from moving downwards and ensuring that the conveying device is stuck on the escalator to prevent it from sliding down the escalator and causing a safety accident. When the worker moves to the bend of the escalator using the conveying device, the worker needs to rotate and adjust their position to ensure the thrust for translation. The auxiliary rod drives the cam 31 to rotate, and the rotation of the cam 31 causes the pressing part 32 on its side to automatically unfold, increasing the range of motion of the guide rollers 21 on both sides of the escalator. This makes it easier for the guide rollers 21 to adjust their position at the bend of the handrail. At the same time, the moving block 25 causes the moving part of the support rod 5 to extend outward, which can increase the distance between the clamping part 6 and the escalator, avoiding contact between the aluminum alloy door and window and the corner of the escalator, and improving the safety of the transfer. This process does not require removing the entire shell 1, which can ensure that the conveying device can pass smoothly through the corner of the escalator. After passing the corner of the escalator, due to the worker's body position, the auxiliary rod drives the cam 31 to reset, and the elastic part 74 drives the guide rollers 21 on both sides to press against the side of the escalator again through its own elastic force. At this time, it can move upward again.

[0052] In summary, the clamping component 6 of this application can not only clamp aluminum alloy doors and windows, but also various building materials or tools, such as boards, glass, and tiles.

[0053] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
