Description

Technical Field

[0001] The invention relates to the technical field of elevators, in particular to an anti-dumping high-rise elevator structure. Background Art

[0002] Before entering the curing warehouse, building panels, such as insulation panels, need to be lifted to a specified height so as to enter different layers of the curing warehouse. The traditional elevator has a vertically movable pallet with rolling parts on it. After the insulation panel is pushed onto the pallet, it is lifted to a specified height by the pallet and then enters the curing warehouse under the action of the rolling parts.

[0003] However, it was found during use that when the height of the elevator reaches a certain height, there is a greater risk of tipping over. The current anti-tipping method is to connect the top and bottom of the elevator to the track through guide wheels. For example, patent number CN202122439266.4, named a patent for a concrete curing room rail stacker, introduces guide wheels in groups of two, symmetrically arranged on both sides of the top surface of the top plate, and respectively abut against both sides of the overhead rail track, but this method can only prevent tipping in the front and rear directions.

[0004] The connection between the guide wheel and the track will cause a strong inertial force to be generated when the elevator runs along the track and brakes, which will cause the elevator to tip over to the left or right (roll over along the track). The elevator will rotate with one side of the bottom as a fulcrum, and the force will be concentrated on the top track, causing the track to deform or damage, and in severe cases, the elevator will roll over. It can be seen that the rollover of the front and back directions and the left and right directions of high-rise elevators should be given equal attention. However, the current elevators either do not have this function or are arranged separately.

[0005] In addition, the guide wheels of the elevator are connected to the track in such a way that when braking at high speed, due to the action of inertia, the wheels can still slide along the track for a certain distance after being locked, resulting in inaccurate loading position.

[0006] In addition, the way that traditional elevator pallets extend out of the frame to feed materials will also affect the stability of the elevator and cause a tendency to tip forward and backward. Summary of the invention

[0007] In order to solve the technical problems existing in the above-mentioned background technology, the present invention provides an anti-dumping high-rise elevator structure, which adopts a top anti-dumping system to simultaneously solve the rollover problem of the high-rise elevator in the front and back directions and the left and right directions, and cooperates with the bottom anti-dumping system and the bottom fixing system to ensure the operation stability of the high-rise elevator.

[0008] The technical solution of the present invention is as follows:

[0009] An anti-dumping high-rise elevator structure, comprising:

[0010] An outer frame is slidably connected to the third guide rail at the bottom;

[0011] The feeding system is arranged on both sides of the outer frame and can convey materials from bottom to top;

[0012] The top anti-tilt system includes a second guide rail and a side connecting piece. The second guide rail is fixed in front of the outer frame, parallel to the third guide rail, and has a height between the top of the outer frame and the highest discharge position. The number of the side connecting pieces includes at least two pieces. One end of the side connecting piece is connected to the outer frame, and the other end is clamped on the second guide rail.

[0013] The side connecting member includes an L-shaped connecting frame, the vertical section is connected to the outer frame, the two ends of the horizontal section are respectively provided with second rollers, a third roller is provided between the two second rollers, the two second rollers are clamped on both sides of the second guide rail, the third roller is located on the upper side or the lower side of the second guide rail, and the rotating surfaces of the second roller and the third roller can contact the outer surface of the second guide rail;

[0014] Since the deformation of the upper part is much greater than that of the lower part when the elevator tips over, the upper anti-tilt is of utmost importance in the elevator design. The top anti-tilt system of the present invention integrates the second roller and the third roller of different positions and directions on the connecting frame at the same time, and prevents the elevator from tipping over in the front and rear directions by clamping the two second rollers. Moreover, the second guide rail is fixed in front of the outer frame and can be fixedly connected to the maintenance warehouse. Compared with the method of fixing it alone on the top of the outer frame, the strength is effectively guaranteed.

[0015] The design of the third roller can limit the tilting of the elevator to the left or right. Moreover, when the elevator tilts to the left or right, the third roller will slide along the second guide rail, thereby avoiding stress concentration and reducing the impact on the single point of the second guide rail when the elevator tilts, so that the elevator slowly returns to the right position during the sliding process.

[0016] In order to better achieve this technical effect, the two side connecting members are respectively located at the left and right ends of the front side of the outer frame. Their vertical projections are respectively located outside the pulley at the bottom of the outer frame. In this way, when the elevator has a tendency to roll over to the left or right, the third roller under one of the side connecting members will inevitably quickly hit the second guide rail to offset the rollover force.

[0017] The second roller and the third roller are both in clearance fit with the outer surface of the second guide rail. When the elevator moves normally, the side connecting member does not contact the second guide rail and does not generate friction resistance. They only contact when there is a tendency to roll over.

[0018] The axis of the second roller is vertically arranged, and its length is not less than half of the thickness of the second guide rail, so as to provide a contact area as large as possible and avoid deformation of the second guide rail caused by excessive local force.

[0019] The third roller axis is perpendicular to the second roller axis and the length direction of the second guide rail, and is assembled at the middle position of the horizontal section of the side connecting member through a fixing member.

[0020] The bottom anti-tilt system cooperates with the top anti-tilt system to provide a better anti-tilt effect. It specifically includes a number of card plates, which are scattered around the outer frame. The upper end of the card plate is connected to the bottom of the outer frame, and the lower end is clamped on the third guide rail and has a clearance with the third guide rail. An opening is set at the clamping point between the card plate and the third guide rail, and the inner size of the opening is larger than the outer size.

[0021] The cross section of the third guide rail is I-shaped, and the lower end of the clamping plate is clamped in the middle position of the third guide rail.

[0022] The third guide rails include at least two, and the clamping plates include at least four, which are installed at the bottom corner of the outer frame.

[0023] Through the design of the bottom anti-tilt system, when the elevator slides normally, the pallet will not contact the third guide rail and no friction resistance will be generated.

[0024] When the elevator has a tendency to tip over in the front-back direction, the front end or the rear end of the pallet abuts against the side of the third guide rail, but cannot be separated from the third guide rail, which will prevent the elevator from continuing to tip over.

[0025] When the elevator has a tendency to tip over in the left or right direction, the clamping plate and the third guide rail are matched with each other, and the uppermost end of the clamping plate opening will quickly abut against the third guide rail, thereby preventing the elevator from tipping over.

[0026] The outer frame can adopt a common rectangular frame structure, which is easy to manufacture, with feeding at the bottom of the rear end and discharging at the upper part of the front end, and the sliding direction is along the left and right direction.

[0027] In order to further slow down the rollover tendency of the elevator when braking, the present invention also designs a bottom fixing system, which includes:

[0028] The bottom support is fixed on the ground and is generally located at a fixed feeding and discharging position.

[0029] A pushing unit is mounted on the lower end of the outer frame through a first mounting seat;

[0030] The clamping unit comprises a second mounting seat, a first clamping jaw and a second clamping jaw, wherein the second mounting seat is mounted at the lower end of the outer frame, the first clamping jaw and the second clamping jaw are in an L-shaped structure arranged opposite to each other, and the inflection points are respectively rotatably connected to the left and right ends of the lower part of the second mounting seat;

[0031] A connecting pin is provided at one end of the first clamping jaw close to the second clamping jaw, and an end of the first clamping jaw away from the second clamping jaw is connected to a pushing unit;

[0032] The second clamping jaw is provided with a sliding groove at one end close to the first clamping jaw, and the connecting pin is located in the sliding groove;

[0033] The pushing unit and the clamping unit are arranged along the length direction of the third guide rail. The clamping unit can be clamped on both sides of the bottom support under the action of the pushing unit, and the maximum height of the clamping unit in the opened state is greater than the height of the bottom support.

[0034] Through the design of the bottom fixing system, when the elevator slides normally, the pushing unit pushes the clamping unit to open to avoid the bottom support. After reaching the designated position and braking, the pushing unit pushes the first clamping jaw to rotate downward, and the movement of the connecting pin in the slide groove pushes the second clamping jaw to move downward, so that the lower ends of the two clamping jaws are squeezed on the bottom support, thereby fixing the elevator in place and preventing it from sliding relative to the third guide rail.

[0035] A transfer system is arranged in the middle of the bottom of the outer frame, which can temporarily store materials, and the feeding system can drive the materials temporarily stored on the transfer system to move upwards.

[0036] A pushing system is provided under the top of the outer frame to push out the materials carried by the loading system, replacing the tray extension to avoid the instability of the outer frame caused by the extension action.

[0037] Through the above design, the anti-tipping high-rise elevator structure of the present invention creatively designs a top anti-tipping system, a bottom anti-tipping system and a bottom fixing system. Through the coordinated cooperation of the three, it can play a good inhibitory effect on the tipping tendency in all directions generated during the operation of the elevator.

[0038] During normal operation, the bottom fixing system firmly fixes the bottom of the elevator. The top anti-tilt system and the bottom anti-tilt system can immediately contact the second guide rail or the third guide rail when the elevator begins to tip over, thereby suppressing the tipping trend.

[0039] When the elevator switches its working position and brakes, the bottom fixing system fixes the bottom of the elevator, and the top will sway left and right relatively greatly. The two side connecting parts of the top anti-tilt system are respectively located at the left and right ends of the front side of the outer frame, and their vertical projections are respectively located on the outside of the bottom pulley of the outer frame. In this way, when the elevator has a tendency to roll over to the left or right, the third roller under one of the side connecting parts will inevitably quickly hit the second guide rail to offset the rollover force. Then, the axis of the third roller is perpendicular to the axis of the second roller and the length direction of the second guide rail, and is assembled in the middle position of the horizontal section of the side connecting part through the fixing part, and has space for upward and downward movement. That is, a buffer margin is provided to mitigate the excessive local impact that directly breaks the connecting shaft of the third roller, which can provide effective buffering for the elevator while also increasing the service life of the side connecting parts.

[0063] See also Figure 1 and Figure 2 , an anti-dumping high-rise elevator structure, generally used for lifting materials in high-rise buildings above 30 floors. The specific structure includes an outer frame 1, a feeding system 2, a transfer system 3, a pushing system 4, a top anti-dumping system 5, a bottom anti-dumping system 6, a bottom fixing system 7 and a third guide rail 8.

[0064] The specific structure of each part is introduced below with reference to the attached drawings, and the material conveying is taken as an example of the insulation board.

[0065] The bottom of the outer frame 1 is slidably connected to the third guide rail 8 at the bottom through a pulley.

[0066] The outer frame 1 can adopt a common rectangular frame structure, which is easy to manufacture, with feeding at the bottom of the rear end and discharging at the upper part of the front end, and the sliding direction is along the left and right direction.

[0067] See also Figure 3 , Figure 5 and Figure 6 The feeding system 2 is arranged on both sides of the outer frame 1 and can transfer materials from bottom to top.

[0068] The feeding system 2 includes a first transmission assembly 21 , a support member 22 and a power distribution unit 23 .

[0069] Among them, the first transmission component 21 adopts a chain transmission method, is arranged vertically and parallel to the third guide rail 8, and is arranged at the four corners of the outer frame 1 respectively. A number of parallel arranged support members 22 are connected between the front and rear first transmission components 21, and the several support members 22 are evenly spaced on the chain.

[0070] Rollers are respectively disposed at both ends of each support member 22 , and the rollers on the inner support member 22 are located above the support member 22 , while the rollers on the outer support member 22 are located below the support member 22 .

[0071] The power distribution unit 23 is located at the top of the outer frame. Through a motor, it drives two meshing gears to rotate synchronously in opposite directions, and then drives the first transmission components 21 on both sides of the outer frame 1 to move synchronously, so that the material can be smoothly moved upward under the support of the left and right support members 22.

[0072] See also Figure 5-Figure 7 The top anti-tilt system 5 includes a second guide rail 51 and a side connecting member 52. The second guide rail 51 is fixed in front of the outer frame 1, parallel to the third guide rail 8, and is not directly connected to the outer frame 1, but fixed on the top of the maintenance warehouse and fixedly connected to the strongest maintenance warehouse. Compared with the method of fixing it alone on the top of the outer frame 1, the strength is effectively guaranteed.

[0073] In this embodiment, the second guide rail 51 adopts a rectangular tube structure, which is convenient for use with the side connecting piece 52. Its installation height is between the top of the outer frame 1 and the highest discharge position, and second baffles 511 are provided at both ends.

[0074] In this embodiment, two side connecting members 52 are provided, which are respectively located on the vertical brackets on both sides of the upper front part of the outer frame 1. One end of the side connecting member 52 is connected to the outer frame 1, and the other end is clamped on the second guide rail 51, and a gap is left between the side connecting member 52 and the second guide rail 51 in a natural state. The elevator does not contact the second guide rail 51 during normal movement, reducing the influence of friction resistance. Only when a tipping trend is about to occur, the side connecting member 52 will contact the second guide rail 51 and offset the tipping force.

[0075] See also Figure 7 The side connecting member 52 includes an L-shaped connecting frame 521, including a vertical section and a horizontal section, and reinforcing ribs are connected on both sides. The vertical section is connected to the outer frame 1, and the front and rear ends of the horizontal section are respectively provided with second rollers 522, and a third roller 523 is provided between the two second rollers 522. A hole is opened in the middle of the horizontal section, and mounting seats are installed on both sides of the hole. The third roller 523 is located in the hole, and its rotation axis is inserted into the mounting seats on both sides.

[0076] The two second rollers 522 are clamped on the front and rear sides of the second guide rail 51, and the third roller 523 is located on the upper side of the second guide rail 51. The rotating surfaces of the second rollers 522 and the third rollers 523 can contact the outer surface of the second guide rail 51, and when in slight contact, they can roll and slide on the outer surface of the second guide rail 51.

[0077] Since the deformation of the upper part is much greater than that of the lower part when the elevator tipped over, the upper anti-tilt is the top priority in the elevator design. The top anti-tilt system 5 of the present invention integrates the second roller 522 and the third roller 523 of different positions and directions on the connecting frame 521, and the two second rollers 522 are clamped to prevent the elevator from tipping over in the front and rear directions.

[0078] The design of the third roller 523 can limit the tilting of the elevator to the left or right, and when the elevator tilts to the left or right, the third roller 523 will slide along the second guide rail 51, thereby avoiding stress concentration and reducing the impact on a single point of the second guide rail 51 when the elevator tilts, so that the elevator slowly returns to the right position during the sliding process. In addition, second baffles 511 are respectively provided at the left and right ends of the second guide rail 51 to prevent the side connection member 52 from sliding out of the second guide rail 51.

[0079] In order to better achieve the above technical effects, the two side connecting members 52 are respectively located at the left and right ends of the front side of the outer frame 1. Their vertical projections are respectively located outside the bottom pulley of the outer frame 1. In this way, when the elevator has a tendency to roll over to the left or right, the third roller 523 under one of the side connecting members 52 will inevitably quickly abut against the second guide rail 51 to offset the rollover force.

[0080] The axis of the second roller 522 is vertically arranged, and the length thereof is not less than half the thickness of the second guide rail 51 , so as to provide a contact area as large as possible and avoid deformation of the second guide rail 51 caused by excessive local force.

[0081] The axis of the third roller 523 is perpendicular to the axis of the second roller 522 and the length direction of the second guide rail 51 .

[0082] See also Figure 8 and Fig. 9 The bottom anti-tilt system 6 cooperates with the top anti-tilt system 5 to provide a better anti-tilt effect. It specifically includes four card plates 61, which are dispersed at the four corners of the bottom of the outer frame 1 that contact the third guide rail 8. The card plate 61 is a vertical plate, the upper end of which is connected to the outer side of the bottom of the outer frame 1, and the lower end is clamped on the third guide rail 8 and has a clearance fit with the third guide rail 8. An opening is set at the clamping position of the card plate 61 and the third guide rail 8, and the inner size of the opening is larger than the outer size;

[0083] The cross section of the third guide rail 8 is I-shaped. The shape of the opening at the lower end of the clamping plate 61 matches the shape of the upper portion of the third guide rail 8 , and the bottom is clamped in the middle position of the third guide rail 8 .

[0084] There are three third guide rails 8 , which are respectively located at the front, rear and middle positions of the bottom of the outer frame 1 .

[0085] Through the design of the bottom anti-tilt system 6, when the elevator is sliding normally, the clamping plate 61 will not contact the third guide rail 8, and no friction resistance will be generated. In addition, the clearance between the clamping plate 61 and the third guide rail 8 will also push away obstacles such as bolts on the third guide rail 8, preventing the elevator from tipping over when it suddenly encounters obstacles during movement.

[0086] When the lift has a tendency to tip over in the front-to-back direction, the front end or rear end of the clamping plate 61 abuts against the side of the third guide rail 8, but cannot be separated from the third guide rail 8, which will prevent the lift from continuing to tip over.

[0087] When the elevator has a tendency to tip over in the left-right direction, the clamping plate 61 and the third guide rail 8 are clearance-matched, and the uppermost end of the opening of the clamping plate 61 will quickly abut against the third guide rail 8, thereby preventing the elevator from tipping over.

[0088] In order to further slow down the rollover tendency of the elevator when braking, the present invention also designs a bottom fixing system 7, see Figure 10-12 , the bottom fixing system 7 comprises:

[0089] The bottom support 74 is fixed on the ground and is generally located at a fixed feeding and discharging position.

[0090] The pushing unit 72 is mounted on the lower end of the outer frame 1 through the first mounting seat 73;

[0091] The clamping unit 71 includes a second mounting seat 711, a first clamping jaw 712 and a second clamping jaw 713. The second mounting seat 711 is mounted at the lower end of the outer frame 1. The first clamping jaw 712 and the second clamping jaw 713 are relatively arranged L-shaped structures, and the inflection points are respectively rotatably connected to the left and right ends of the lower part of the second mounting seat 711;

[0092] The first clamping jaw 712 is provided with a connecting pin at one end close to the second clamping jaw 713 , and is connected to the pushing unit 72 at one end away from the second clamping jaw 713 ;

[0093] The second clamping jaw 713 is provided with a sliding groove at one end close to the first clamping jaw 712, and the connecting pin is located in the sliding groove;

[0094] The arrangement direction of the pushing unit 72 and the clamping unit 71 is along the length direction of the third guide rail 8 . The clamping unit 71 can be clamped on both sides of the bottom support 74 under the action of the pushing unit 72 , and the maximum height of the clamping unit 71 in the opened state is greater than the height of the bottom support 74 .

[0095] In order to increase the clamping force, the inner sides of the lower ends of the first clamping jaw 712 and the second clamping jaw 713 are respectively connected with clamping plates, and the length of the clamping plates is greater than the side width of the bottom support 71 to increase the contact area between the two.

[0096] Through the design of the bottom fixing system 7, when the elevator slides normally, the pushing unit 72 pushes the clamping unit 71 to open to avoid the bottom support 74. After reaching the designated position and braking, the pushing unit 72 pushes the first clamping jaw 712 to rotate downward, and the movement of the connecting pin in the slide groove pushes the second clamping jaw 713 to move downward as well, so that the lower ends of the two clamping jaws are squeezed on the bottom support 74, thereby fixing the elevator in place and preventing it from sliding relative to the third guide rail 8.

[0097] The present invention also specially designs a new feeding and discharging method to reduce the shaking of the outer frame 1 caused by the frequent extension of components from the inner part of the outer frame 1 to the outer part. Specifically:

[0098] See also Figure 3 A transfer system 3 is provided in the middle of the bottom of the outer frame 1, which can temporarily store materials. The width is smaller than the distance between two oppositely arranged support members 22 in the feeding system 2. The feeding system 2 can drive the materials temporarily stored on the transfer system 3 to move upward.

[0099] The transfer system 3 includes a lower bracket 31, which is fixed above the bottom of the outer frame 1, and a second transmission assembly 32 is arranged on it, which is arranged perpendicular to the third guide rail 8. Side supports 33 are respectively arranged on both sides of the second transmission assembly 32, and their heights are lower than the second transmission assembly 32, but the difference is not large. Limiting members 34 are connected to the front ends of the two side supports 33.

[0100] In this embodiment, the second transmission assembly 32 adopts belt drive, the side support 33 adopts channel steel and is arranged parallel to the second transmission assembly 32, and the limiter is an angle iron and is arranged parallel to the third guide rail 8.

[0101] See also Figure 1 The insulation board enters from the rear of the second transmission assembly 32. Since the middle of the belt drive will sag, the front end of the insulation board will move forward along the side support 33 after entering the transfer system 3 until it stops at the stopper 34. Then, the two support members 22 of the feeding system 2 move upward from bottom to top against both sides of the insulation board to a specified height. Repeat the above steps for the next insulation board.

[0102] See also Figure 13-Figure 20 A pushing system 4 is provided below the top of the outer frame 1 for pushing out the materials carried by the loading system 2 to replace the tray extending outward, thereby avoiding the instability of the outer frame 1 caused by the extending action.

[0103] The pushing system 4 includes a third transmission assembly 41, which adopts chain transmission, is arranged perpendicular to the third guide rail 8, and is installed on a pushing bracket 42. A chain supporting unit 46 is installed at the bottom of the pushing bracket 42 to prevent the chain from sagging.

[0104] See also Figure 18-Figure 20 A plurality of groups of long pins 463 are arranged at intervals on the chain of the third transmission assembly 41, with chains extending from both ends. The pusher bracket 42 is connected to rectangular tubes 461 on both sides of the lower transmission chain, and a support plate 462 is provided at the bottom of the rectangular tube 461. The support plate 462 and the rectangular tube 461 are fixed to the pusher bracket 42 together with bolts, and the support plate 462 extends in the direction of the chain so that the long pins 463 fall on the support plate 462, thereby preventing the lower chain from sagging.

[0105] A pushing piece 43 is connected below the third transmission assembly 41, and first guide rails 421 are respectively provided at the lower ends of both sides of the pushing bracket 42. The front end of the first guide rail 421 is closed with a first baffle 422. The pushing piece 43 moves along the first guide rail 421 driven by the third transmission assembly 41, and can push the insulation board out of the elevator from the back to the front.

[0106] The up and down movement of the pushing system 4 is achieved by the limiting unit 44 and the locking unit 45 .

[0107] See also Fig.13 and Fig.14 The limiting unit 44 includes a transmission shaft and a gear 441 connected at the front and rear ends of the pushing bracket 42. Two transmission shafts are provided at each end, which are arranged parallel to the direction of the third guide rail 8 and are driven by a motor to rotate synchronously. The gears are located at the end of the transmission shaft and are at the outermost positions on both sides of the pushing system 4. A vertically arranged rack 443 is provided next to the first transmission assembly 21, with a total of four racks, the front and rear two of which are a group and arranged opposite to each other. The gears 441 are all located on the inner side of the rack 443, thereby limiting the displacement of the pushing bracket 42 in the front and rear directions.

[0108] A first roller 442 is also connected to the bottom of the pusher bracket 42 below the gear 441 . The axis of the first roller 442 is perpendicular to the third guide rail 8 , and the outer surface is aligned with the side of the rack 443 , thereby limiting the displacement of the pusher bracket 43 in the left and right directions.
