Description

Technical Field

[0001] The invention relates to the technical field of door and window conveying, and in particular to a high-stability safety conveying device for conveying aluminum alloy doors and windows by stairs. Background Art

[0002] Aluminum alloy doors and windows refer to doors and windows with aluminum alloy as the main structural material. Aluminum alloy is a lightweight, high-strength metal material composed of pure aluminum and other elements (such as copper, manganese, magnesium, silicon, etc.). Aluminum alloy has low density but high strength, making doors and windows both light and durable.

[0003] At present, with the renovation or improvement of people's houses, many old buildings or low-rise buildings may not have elevators installed. Therefore, building materials such as aluminum alloy doors and windows need to be carried to designated floors via stairs. At some construction sites, due to space limitations or construction safety considerations, some elevators cannot provide people with the ability to carry aluminum alloy doors and windows, so workers need to carry them to designated floors from the stairs, resulting in low overall transportation efficiency and increased labor intensity for workers.

[0004] In the prior art, since workers can only carry the device from the stairs, in order to reduce the labor intensity of the workers, there is already a device to help workers carry the aluminum alloy doors and windows from the stairs. Specifically, the Chinese patent publication number is CN113371387B, which uses a cross carrying frame to clamp and fix the aluminum alloy doors and windows, and the rubber pad can be added with a belt tied around the waist. The U-shaped plate slides on the stair handrail, so that when the porter holds the device to go upstairs, his body will push the push rod to bring the entire device up along the stair handrail, reducing the difficulty of the workers' carrying. It can not only achieve the effect of single-person carrying, but also solve the problem of the aluminum alloy doors and windows colliding with the ground.

[0005] However, a careful study of the above scheme shows that there are still some shortcomings in this scheme. Specifically, although the U-shaped plate and trapezoidal clamps are used to fit and slide the stair handrails, the labor intensity of workers in carrying the stairs can be reduced, but the stairs are multi-layered and staggered in design. When the U-shaped plate moves to the corner of the stairs, the trapezoidal clamps need to be manually adjusted by personnel, which makes it difficult to change the direction of the U-shaped plate, wastes too much time, and cannot be smoothly turned to the other handrail, resulting in low efficiency for workers in carrying aluminum alloy doors and windows. At the same time, the handrail is easily damaged during the sliding process, such as scratches and cracks on the handrail surface.

[0006] Therefore, when workers carry aluminum alloy doors and windows on stairs, the present application aims to improve the efficiency of workers carrying aluminum alloy doors and windows with the help of handrails when turning corners, while reducing the problem of surface damage to the handrails. Summary of the invention

[0007] The main purpose of the present invention is to provide a high-stability and safe conveying device for conveying aluminum alloy doors and windows on stairs, aiming to improve the efficiency of workers in carrying aluminum alloy doors and windows with the help of handrails when turning corners, while reducing the problem of damage to the handrail surface.

[0008] In order to achieve the above object, the present invention proposes a high-stability and safe conveying equipment for conveying aluminum alloy doors and windows through stairs, comprising:

[0009] a shell, open on one side;

[0010] A support member, mounted on a side of the housing away from the opening, for clamping and supporting the door and window;

[0011] A pair of side rollers are arranged on the open side of the shell, each of the side rollers includes at least one guide roller that can fit the side of the handrail, a driving gear fixed on the top of the guide roller, and a connecting gear meshing with the driving gear, and a U-shaped frame is rotatably arranged on the opposite sides of the two connecting gears;

[0012] A main frame is arranged between the pair of side rollers, a guide shaft is arranged 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] The thrust joint is rotatably connected to the top end of the shell body, and is used to connect the auxiliary rod and help to tilt and apply force.

[0014] Furthermore, when each of the side roller members is provided with two guide rollers, a connecting piece is provided between the centers of the driving gear and the connecting gear.

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

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

[0017] Furthermore, an extrusion piece is provided at one end of the U-shaped frame close to the main frame, and a cam is fixedly installed at one end of the thrust joint passing through the shell, and the cam is fitted with an outer wall of the extrusion piece to adjust the distance between the U-shaped frame and the main frame.

[0018] Furthermore, bearing members are provided at both ends of the main frame, and the bearing members include a mounting plate detachably fixed to the main frame, a bearing frame fixed to the bottom end of the mounting plate, and a guide wheel rotatably arranged at the bottom end of the bearing frame, and the guide wheel is used to fit the stairs.

[0019] Furthermore, both sides of the support frame away from the guide wheel are provided with support blocks, and the support blocks are clamped with the main frame.

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

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

[0022] Furthermore, a ratchet device is provided on one side of the U-shaped frame facing the connecting gear to limit the reverse rotation of the connecting gear.

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

[0024] The present invention installs the auxiliary rod through the thrust joint, which is convenient for workers to apply force. The support parts are placed on the aluminum alloy doors and windows, and the side roller parts are distributed on both sides of the main frame, so that the side roller parts can be pressed against the sides of the handrails. At the same time, the side roller parts can move toward the two sides of the escalator. When the conveying device moves up, the guide rollers can move with the turning parts of the escalator, thereby increasing the activity space of the guide rollers and the turning parts of the handrails, ensuring that the conveying device can pass smoothly. The whole process does not require human transportation or large-scale adjustment, which reduces the labor intensity of workers, improves the efficiency of workers in carrying the aluminum alloy doors and windows with the help of handrails when turning corners, and alleviates the problem of surface damage of the handrails.

[0025] An elastic part is provided between the guide shafts on both sides of the main frame. The elastic part is used to pull the guide shafts at both ends. At the same time, an extrusion part is provided at the end of the U-shaped frame close to the main frame. A cam is fixedly installed at one end of the thrust joint that passes through the shell. The cam fits with the outer wall of the extrusion part. The worker ensures the translational thrust to automatically drive the cam to rotate. The rotation of the cam drives the extrusion part close to its own side to automatically unfold without manual adjustment. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention is described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the following specific embodiments are only used to explain the present invention and do not constitute a limitation to the present invention.

[0038] like Figures 1 to 3 As shown, a high-stability and safe conveying equipment for conveying aluminum alloy doors and windows on stairs includes a shell 1, a support, a pair of side rollers 2, a main frame 7 and a thrust joint 3, one side of the shell 1 is open; the support is installed on the side of the shell 1 away from the open side, for clamping and supporting the door and window; a pair of side rollers 2 are arranged on the open side of the shell 1, each side roller 2 includes at least one guide roller 21 that can fit on the side of the handrail, a driving gear 22 fixed to the top of the guide roller 21 and a connecting gear 23 meshing with the driving gear 22, and a U-shaped frame 24 is rotatably arranged on the opposite sides of the two connecting gears 23; the main frame 7 is arranged between the pair of side rollers 2 and fixed to the shell 1, such as bolt fixation or plug fixation, and 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 joint 3 is rotatably connected to the top of the shell 1, for connecting the auxiliary rod and helping to tilt and apply force. Among them, the conveying equipment is divided into two directions, one of which is the upward direction along the stairs, and the other is the unfolding direction perpendicular to the escalator. The shell 1 is provided with a through groove along the upward direction, so that the shell 1 can cover both sides of the escalator along the unfolding direction. The shell 1 is also provided with an observation groove in the unfolding direction to facilitate viewing the specific situation of the side roller 2. The support can clamp the aluminum alloy doors and windows, and after the support is clamped, it can realize the transportation operation together with the shell 1 when it moves upward, thereby reducing the burden on workers.

[0039] like Figure 1 As shown, specifically, the support member can be supported by a lever, or by a frame supported by a fixed outer periphery of the thrust joint 3, such as using ropes to hoist aluminum alloy doors and windows, and setting a support point at the edge of the shell 1. In the present application, the support member includes a support seat 4, a support rod 5 and a clamping member 6, wherein the support seat 4 is fixed to the top of the shell 1, at least two are set, and are symmetrically arranged along the unfolding direction, one end of the support rod 5 is rotatably set on the support seat 4, and the other end is fixed to the clamping member 6, and the middle part of the support seat 4 is at least placed on one support seat 4 to play a supporting role, and the clamping member 6 Used for clamping aluminum alloy doors and windows. Since most of aluminum alloy doors and windows are square, threaded clamping is adopted. Cross clamps, hydraulic clamps, inclined transport plates or other forms can also be used. If cross clamps are used, the aluminum alloy doors and windows are clamped on all sides to maintain overall stability. The hydraulic clamps can be cross-shaped, or only clamp the two sides of the aluminum alloy doors and windows. If an inclined transport plate is used, the transport plate and the shell 1 are tilted so that the aluminum alloy doors and windows are embedded in 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 is also convenient for taking and placing during transportation.

[0040] like Figures 1 to 3 As shown, as an embodiment of the present application, the side roller member 2 can adopt 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 driving gear 22 and the connecting gear 23 are distributed along the unfolding direction, and only two guide rollers 21 are used to attach to the two sides of the handrail respectively, so as to achieve 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 where the middle of the two guide rollers 21 are located, and transmission with the handrail can also be achieved. It is preferred to clamp the single guide roller 21 on the handrail Inward direction; if two guide rollers 21 are set on both sides of the handrail, a connecting piece 27 is set between the center of the driving gear 22 and the connecting gear 23, and the connecting piece 27 is used to connect the driving gear 22 and the connecting gear 23 to ensure that the driving gear 22 surrounds the center of the connecting gear 23, and the guide rollers 21 on each side are respectively attached to the side of the handrail to ensure the transmission stability of the conveying device. Since the driving gear 22 and the connecting gear 23 are meshed with each other, the guide roller 21 can rotate along the center of the connecting gear 23 when it is squeezed by the handrail, thereby avoiding the corner of the escalator and satisfying the process of the conveying device moving up along the escalator.

[0041] like Figure 1As shown, as an embodiment of the present application, the thrust joint 3 is a joint installed on the top of the shell 1. The thrust joint 3 can be directly connected to the auxiliary rod. Specifically, it can be rotated with the auxiliary rod thread, or it can be fixed by a pin or a snap connection. The auxiliary rod can be rotated to adjust the orientation, and the auxiliary rod is pressed against the worker's abdomen or chest by a strap or a rubber sleeve, thereby driving the shell 1 to move forward in the upward direction, greatly relieving the labor intensity of the workers.

[0042] like Figure 4 and Figure 5 As shown, as an embodiment of the present application, an elastic member 74 is provided between the guide shafts 75 on both sides of the main frame 7, and the elastic member 74 is used to pull the guide shafts 75 at both ends, and the guide shafts 75 are slidably connected with the main frame 7, so as to cause the side rollers 2 on both sides to move closer to the main frame 7, thereby generating a lateral force to clamp the escalator, and maintaining the clamping degree and movement flexibility of the side rollers 2 on the handrail. It should be noted that the elastic member 74 is preferably pulled by a spring to ensure the elastic force between the elastic members 74 on both sides, and can also be replaced by an elastic belt or a leaf spring, which can be set according to 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, wherein 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 opened 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, so that the sliding of the guide shaft 75 on the inner wall of the guide plate 72 is interfered, affecting the range of movement, and also squeezing 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, which can be fixed only to the main frame 7, or fixed to the guide plate 72 installed on the inner wall of the main frame 7, to increase the force of the column 73 along the horizontal direction, and also improve the structural strength of the guide plate 72 and the column 73.

[0044] like Figure 1 , Figure 2 and Figures 4 to 6As shown, as an embodiment of the present application, an extrusion piece 32 is provided at one end of the U-shaped frame 24 close to the main frame 7, and a cam 31 is fixedly installed at one end of the thrust joint 3 that passes through the shell 1. The cam 31 fits the outer wall of the extrusion piece 32 to adjust the distance between the U-shaped frame 24 and the main frame 7. Among them, 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 squeezes the extrusion piece 32, so that the squeezed extrusion piece 32 gradually moves along the expansion direction, thereby driving the corresponding side roller 2 to expand. At this time, the elastic member 74 is subjected to tension. This process can increase the range of movement of the guide rollers 21 on both sides of the escalator. When passing through the turning point of the escalator, the guide rollers 21 on both sides can be more easily expanded, so that the conveying device can pass through the turning point of the escalator more conveniently. When the guide rollers 21 with an increased range of movement pass through the outer part of the escalator, the cam 31 gradually resets, and the elastic member 74 is pulled by itself. The elastic force drives the guide rollers 21 on both sides to press the sides of the escalator again, and the escalator can be moved up again for transportation. It should be noted that the rotation of the cam 31 is relatively synchronized with the thrust joint 3. The worker pushes up through the auxiliary rod, and the auxiliary rod tilts upward to drive the side roller 2 to move up. When the worker passes the corner of the escalator, he will stride forward and speed up his pace, and drive the thrust joint 3 to rotate through the auxiliary rod, thereby driving the cam 31 to rotate at a larger angle. The cam 31 will squeeze the extrusion piece 32 on one side, preferably squeezing the extrusion piece 32 on the worker's side, so that the U-shaped frame 24 gradually moves in the unfolding direction, realizing automatic unfolding operation without manual adjustment.

[0045] Specifically, the extrusion piece 32 can be designed to be integrally formed with the U-shaped frame 24, that is, a convex rib is set on the edge of the U-shaped frame 24 to facilitate the extrusion and expansion of the cam 31. In the present application, the extrusion piece 32 preferably adopts a wheel so that there is rolling friction between the wheel and the cam 31 to reduce friction. In addition, the extrusion piece 32 can also be a long strip or arc block fixed to the end of the U-shaped frame 24 close to the cam 31. It should be noted that the cam 31 can be set on both sides of the main frame 7, or only on one side of the main frame 7, such as splitting the cam 31 into two parts, the first part is rotatably set on one side of the main frame 7, and the first part is in contact with the extrusion piece 32 on one side, and the other part is set on the other side of the main frame 7 and in contact with the extrusion piece 32 on the other side, so as to drive the side roller 2 to move back and forth along the unfolding direction, or the cam 31 is rotatably set on both sides of the top and bottom of the main frame 7, and at least one side of the U-shaped frame 24 is provided with an extrusion piece 32. In the present application, it is preferred to rotatably set the cam 31 at the top of the main frame 7, and the extrusion pieces 32 are all set at the top of the U-shaped frame 24, and the cam 31 is in contact with the U-shaped frames 24 on both sides at the same time.

[0046] like Figure 6 , Figure 8 and Fig. 9As shown, bearing members 76 are provided at both ends of the main frame 7, and the bearing members 76 include a mounting plate 761 detachably fixed on the main frame 7, a bearing frame 762 fixed at the bottom end of the mounting plate 761, and a guide wheel 763 rotatably arranged at the bottom end of the bearing frame 762, and the guide wheel 763 is used to fit the stairs. Among them, in order to improve the carrying capacity of the conveying device, guide wheels 763 are arranged at both ends of the main frame 7. The guide wheels 763 fit the surface of the escalator to reduce the wear of the escalator and also reduce the resistance of the conveying device in the upward direction. Specifically, the end of the mounting plate 761 close to the column 73 is arc-shaped and fits against the outer wall of the column 73. The mounting plate 761 and the main frame 7 are detachable and can be fixed by bolts, plug-in or snap-in. In the present application, a sliding groove for plugging in the mounting plate 761 is provided on the inner wall of the main frame 7. The mounting plate 761 can be pre-fixed by snap-in 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 wheel 763 to move to the end of the main frame 7 through the load-bearing frame 762, thereby completing the installation of the guide wheel 763. The overall installation method is simple, and there is no need to install the guide wheel 763 separately, thereby reducing the number of assembly steps.

[0047] Specifically, blocks 764 are provided on both sides of the support frame 762 away from the guide wheel 763, and the blocks 764 are clamped 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, and the blocks 764 are also clamped on the end of the main frame 7. The blocks 764 are located on the lower side of the main frame 7, so that when the guide wheel 763 contacts the surface of the escalator, the blocks 764 can provide sufficient bearing capacity, and the bearing capacity of the guide wheel 763 can be fully transmitted to the main frame 7; the mounting plate 761 and the mounting plate 761 are detachably connected. Because the support frame 762 is symmetrically arranged, its two ends can be bent toward or away from each other, and can be fastened to the mounting plate 761 with bolts. In the present application, it is preferred that the mounting plate 761, the support frame 762 and the guide wheel 763 are integrally formed, which greatly reduces the difficulty of assembly, saves production costs, and also improves the structural strength.

[0048] like Figure 2 , Figure 4 , Figure 6 , Figure 8 and Fig. 9As shown, as an embodiment of the present application, an end platform 71 is further provided at one end of the main frame 7 close to the supporting 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 direction of the mounting plate 761. At this time, the carrier block 764 leans against the lower side of the end platform 71, so that the carrier block 764 directly leans against the bottom of the end platform 71. The bearing capacity of the guide wheel 763 can be fully transmitted to the end platform 71. A groove for moving the guide wheel 763 is opened on the end platform 71 to facilitate assembly. The setting of the end platform 71 can increase the distance between the overall main frame 7 and the escalator, maintain the center of gravity of the conveying device, improve the stability of the movement, and also ensure the assembly space of the guide wheel 763.

[0049] like Figure 2 , Figure 3 and Figure 7 As shown, as an embodiment of the present application, a ratchet device is further provided on the side of the U-shaped frame 24 facing the connecting gear 23 to limit the reverse rotation of the connecting gear 23. The ratchet device includes a ratchet, which is assembled on the side of the U-shaped frame 24 facing the connecting gear 23. The ratchet is arranged at the end of the connecting gear 23, so that the ratchet device is hidden in design and easy to assemble. The ratchet device can be used after only assembling the U-shaped frame 24 and the connecting gear 23. When the conveying device is on the inclined surface of the escalator, the worker does not apply a force in the upward direction at this time, and the connecting gear 23 is limited to rotate by the ratchet device. After the connecting gear 23 is restricted, the connecting gear 23 and the driving gear 22 no longer rotate, thereby limiting the guidance of the guide roller 21 and the side of the escalator, thereby preventing the conveying device from slipping off by itself when the workers are resting.

[0050] like Figures 1 to 3As shown, as an embodiment of the present application, the shell 1 is provided with straight grooves in the unfolding direction, and a moving 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 seat 4, and the middle part of the support rod 5 can be supported by the moving block 25. The top of the moving block 25 can be plugged, snapped or slidably connected to the support rod 5. The end of the moving block 25 facing the shell 1 is fixed to the positioning shaft 26, which can be fixed by bolts, or the end of the moving block 25 facing the shell 1 is fixedly connected to the U-shaped frame 24, which can be fixed by welding or bolts. When the side roller 2 faces 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 expansion direction, thereby increasing the supporting force on the clamping member 6, so that the conveying device can support the support rod 5 more stably when passing the corner of the escalator; in the above method, the support rod 5 can adopt 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 doors and windows from touching the corner of the escalator, thereby improving the safety of transportation; since a plurality of support seats 4 are provided, rubber pads or cardboard can be placed on the support seats 4, so that the support rod 5 is pressed on the rubber pads or cardboard, which can increase the fulcrum of the support rod 5 and ensure the supporting capacity.

[0051] When in use, the worker first fixes the auxiliary rod and the thrust joint 3, and then assembles the aluminum alloy door and window on the clamp 6, holds one end of the shell body 1, and moves the shell body 1 in the upward direction through the auxiliary rod, and the guide wheel 763 moves up along the surface of the escalator. At the same time, the guide roller 21 fits on the side of the escalator under the action of the elastic member 74 and the U-shaped frame 24, thereby limiting the overall stability of the conveying device. When the worker takes a break during the upward process, the ratchet device limits the rotation of the connecting gear 23, thereby preventing the guide roller 21 from moving downward, ensuring that the conveying device is stuck on the escalator to avoid sliding down the escalator and causing safety accidents; when the worker moves to the corner of the escalator through the conveying device, the worker ensures the thrust of the translation, and needs to rotate and adjust his own position, That is, the cam 31 is driven to rotate by the auxiliary rod, and the rotation of the cam 31 drives the extrusion piece 32 close to its side to automatically expand, thereby increasing the range of movement of the guide rollers 21 on both sides of the escalator, making it easier for the guide rollers 21 to adjust their positions at the bends of the handrails. At the same time, the moving block 25 drives the moving part of the support rod 5 to extend outward, thereby increasing the distance between the clamping piece 6 and the escalator, avoiding contact between the aluminum alloy doors and windows and the corners of the escalator, and improving the safety of transportation. This process does not require the removal of the entire shell 1, and can ensure that the conveying device passes the corner of the escalator smoothly. After passing the corner of the escalator, due to the body position of the worker, the auxiliary rod drives the cam 31 to reset, and the elastic member 74 drives the guide rollers 21 on both sides to be pressed against the sides of the escalator again through its own elastic force, and can move up again at this time.

[0052] In general, the clamping member 6 of the present application is not only capable of clamping aluminum alloy doors and windows, but can also clamp various materials or tools required for construction, such as plates, glass, tiles, etc.
