Description

Technical Field

[0001] The present invention relates to the field of elevators, and in particular to a wide-door elevator with a protective structure. Background Art

[0002] Elevator refers to a permanent transportation device that serves several specific floors in a building and whose car runs on at least two rows of rigid rails that are perpendicular to the horizontal plane or inclined at an angle of less than 15 degrees to the plumb line;

[0003] A vertical lift has a car that runs between at least two vertical rigid guide rails or guide rails with an inclination angle of less than 15 degrees. The size and structure of the car are convenient for passengers to enter and exit or for loading and unloading goods. It is customary to refer to elevators as a general term for vertical transportation vehicles within a building, regardless of their driving mode.

[0004] Freight elevators are widely used in logistics warehouses, shopping malls, factory workshops and other places. Frequent loading and unloading of goods in and out of the elevator car can easily cause collisions between goods and / or transportation equipment such as forklifts and the car door, landing door, car frame, small door cover, etc., causing deformation or damage to the car door, landing door, car frame, small door cover, increasing the frequency of elevator failures and affecting the normal operation of the freight elevator.

[0005] In addition, there is a gap between the ground and the elevator car when the transport equipment enters the elevator, so the wheels of the transport equipment are easily stuck, requiring the staff to push the equipment vigorously, which can easily cause the goods to overturn and also cause high fatigue intensity for the staff;

[0006] Therefore, we propose a wide-door elevator with a protective structure. Summary of the Invention

[0007] The object of the present invention is to provide a wide-door elevator with a protective structure, which solves the problems raised in the background technology.

[0008] To achieve the above-mentioned object, the present invention provides the following technical solution: a wide-door elevator with a protective structure, comprising an elevator wall fixed to the ground, an elevator door provided on the surface of the elevator wall, landing doors movably connected to both sides of the inner wall of the elevator door, and protective mechanisms fixed to both sides of the surface of the ground corresponding to the elevator door;

[0009] The protective mechanism includes a fixed plate and a movable plate, the fixed plate is fixed to the ground, the movable plate is arranged on one side of the fixed plate, and buffer mechanisms are fixed at the four corners of a side wall of the fixed plate corresponding to the movable plate, and the outer end of the buffer mechanism is fixedly connected to the movable plate.

[0010] By adopting the above technical solution, when the cargo transport equipment and the cargo enter the elevator, the movable plate can limit the transport equipment for protection. At the same time, when the movable plate is impacted, the buffer mechanism will be used for buffering. During the buffering process, the reverse internal force will be given, thereby driving the transport equipment to move, thereby achieving a guiding effect, ensuring that the transport equipment enters the elevator accurately, and avoiding damage to the elevator caused by impact.

[0011] As a preferred embodiment of the present invention, the outer wall of the movable plate is provided with a plurality of evenly distributed strip grooves, and guide rollers are rotatably mounted in the inner cavities of the strip grooves.

[0012] By adopting the above technical solution, the setting of the guide roller can play a good guiding role when limiting the transportation equipment and goods, thereby ensuring that the transportation equipment enters the elevator accurately, while reducing friction and improving the protection effect.

[0013] As a preferred embodiment of the present invention, a first pressure switch is fixed to the middle of a side wall of the fixed plate close to the movable plate, and an alarm is fixed to the outer wall of the elevator wall.

[0014] By adopting the above technical solution, in actual use, when the movable plate is impacted while limiting and guiding the cargo transport equipment, the buffer mechanism can play a good buffering effect. When the cargo is large and difficult to enter and is continuously pushed with force, the movable plate will continue to move, thereby giving the first pressure switch a certain force, thereby activating the alarm to sound an alarm, thereby warning the staff to stop moving the cargo, avoiding the cargo tipping over and the elevator equipment being damaged by a large impact.

[0015] As a preferred embodiment of the present invention, the buffer mechanism includes a sleeve and an insertion rod, the insertion rod is inserted into the sleeve and fixedly connected to an adaptive movable block, a first spring is fixed to one side wall of the movable block, the outer end of the first spring is fixedly connected to the inner wall of the sleeve, one end of the sleeve is fixedly connected to the fixed plate, and one end of the insertion rod is fixedly connected to the corresponding position of the movable plate.

[0016] By adopting the above technical solution, when the movable plate is impacted, the movable plate will drive the insertion rod to push the movable block, thereby compressing the first spring, thereby achieving a buffering effect.

[0017] As a preferred embodiment of the present invention, a gap is provided on the ground near the elevator car, a carrier plate is provided in the gap, a limiting slide groove is provided at the bottom of the inner cavity of the gap, an adaptive limiting slider is inserted into the inner cavity of the limiting slide groove, a second pressure switch is embedded in the top of the limiting slider, the top of the second pressure switch and the bottom of the carrier plate are fixedly connected, an electromagnet is fixed at one end of the inner cavity of the limiting slide groove away from the car, and a magnet block is fixedly embedded on the side wall of the limiting slider close to the electromagnet.

[0018] By adopting the above technical solution, in actual use, when the moving wheel on the front side of the transportation equipment moves to the surface of the carrier plate, a certain pressure will be applied to the second pressure switch, thereby starting the electromagnet to generate a thrust on the magnet block on the side wall of the limit slider, thereby pushing the limit slider to move in the limit slide groove, so that the carrier plate moves and fits into the car, so that the moving wheel of the transportation equipment will not get stuck when entering the car. At the same time, after the front moving wheel enters the car, the carrier plate is not pressed, the electromagnet is powered off, and the carrier plate is reset. When the rear moving wheel moves to the carrier plate again, it will push the carrier plate to fit the car again, thereby ensuring that the transportation equipment moves stably and is not stuck, thereby saving manpower, reducing the labor intensity of the staff, and avoiding the occurrence of cargo tipping.

[0019] As a preferred embodiment of the present invention, an iron plate is fixed to the outer wall of the landing door.

[0020] By adopting the above technical solution and setting the iron plate, the protection effect can be improved.

[0021] As a preferred embodiment of the present invention, the inner wall of the elevator door is fixedly covered with an adaptive iron frame.

[0022] By adopting the above technical solution, the setting of the iron frame can protect the elevator door and improve the impact protection.

[0023] As a preferred embodiment of the present invention, the top of the carrier plate is provided with anti-slip grooves.

[0024] By adopting the above technical solution and setting the anti-skid grooves, the transportation equipment can be prevented from sliding.

[0025] As a preferred embodiment of the present invention, a second spring is fixed to the other side wall of the limiting sliding block, and the outer end of the second spring is fixedly connected to the inner wall of the limiting sliding groove.

[0026] By adopting the above technical solution, when the carrier plate is not under pressure, the electromagnet is powered off, so that the second spring can drive the carrier plate to automatically reset.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] The wide-door elevator with a protective structure of the technical solution of the present application has protective mechanisms on both sides of the elevator door, which can provide good protection when transporting cargo equipment enters the elevator. The guide rollers are provided to provide a certain guiding effect, thereby ensuring that the cargo transport equipment can accurately enter the elevator and avoid collisions with the elevator door, floor door, and car door, thereby avoiding impact damage to the elevator and effectively protecting the elevator.

[0029] When the movable plate is guided and subjected to a large extrusion force, the buffer mechanism can be compressed, thereby exerting pressure on the surface of the first pressure switch, thereby activating the alarm to warn the staff that too much transport equipment and cargo cannot enter the elevator, so that the staff can deal with it in time, thereby avoiding the situation where forced entry causes impact on the elevator, further improving the protection effect;

[0030] When the moving wheel on the front side of the transport equipment moves to the surface of the carrier plate, a certain pressure will be applied to the second pressure switch, which will start the electromagnet to generate a thrust on the magnet block on the side wall of the limit slider, thereby pushing the limit slider to compress the spring, so that the carrier plate and the car fit together, thereby avoiding the formation of gaps and ensuring that the transport equipment moves stably into the car, thereby avoiding jamming, reducing the labor intensity of the staff, and avoiding the occurrence of cargo tipping.

[0042] See also Figure 1-5 The present invention provides a technical solution: a wide-door elevator with a protective structure, comprising an elevator wall 1, the elevator wall 1 being fixed to the ground 2, an elevator door 11 being provided on the surface of the elevator wall 1, and floor doors 12 being movably connected to both sides of the inner wall of the elevator door 11, and protective mechanisms 3 being fixed on the surface of the ground 2 on both sides corresponding to the elevator door 11. In actual use, when equipment transporting goods moves into the elevator, it will be protected by the protective mechanism 3, which can guide the transport equipment and goods, thereby avoiding damage to the elevator caused by impact on the elevator door 11, the floor door 12 and the car door, thereby achieving a good protective limiting effect;

[0043] Furthermore, an iron plate 14 is fixed to the outer wall of the landing door 12. The provision of the iron plate 14 can improve the protection effect;

[0044] Furthermore, the inner wall of the elevator door 11 is fixedly covered with an adaptive iron frame. The setting of the iron frame can protect the elevator door 11 and improve the impact protection.

[0045] like Figure 1 and 2 As shown; the protective mechanism 3 includes a fixed plate 31 and a movable plate 32, the fixed plate 31 is fixed to the ground, the movable plate 32 is arranged on one side of the fixed plate 31, and the four corners of the side wall of the fixed plate 31 corresponding to the movable plate 32 are fixed with a buffer mechanism 4, and the outer end of the buffer mechanism 4 is fixedly connected to the movable plate 32;

[0046] When the cargo transport equipment and the cargo enter the elevator, the movable plate 32 can limit the transport equipment and protect it. At the same time, when the movable plate 32 is impacted, the buffer mechanism 4 will be used to buffer it. During the buffering process, the reverse force will be applied, thereby driving the transport equipment to move, thereby achieving a guiding effect, ensuring that the transport equipment enters the elevator accurately, and avoiding damage to the elevator caused by impact.

[0047] Furthermore, the outer wall of the movable plate 32 is provided with a plurality of evenly distributed strip grooves 33, and the inner cavity of the strip grooves 33 is rotatably mounted with guide rollers 34. The arrangement of the guide rollers 34 enables good guidance when limiting the position of the transport equipment and cargo, thereby ensuring that the transport equipment enters the elevator accurately, while also reducing friction and improving the protection effect;

[0048] Furthermore, a first pressure switch 35 is fixed in the middle of one side wall of the fixed plate 31 near the movable plate 32, and an alarm 13 is fixed on the outer wall of the elevator wall 1. In actual use, when the movable plate 32 is impacted while limiting the guide of the cargo transport equipment, the buffer mechanism 4 can play a good buffering effect. When the cargo is large and difficult to enter and is continuously pushed with force, the movable plate 32 will continue to move, thereby applying a certain force to the first pressure switch 35, thereby activating the alarm 13 to sound an alarm, thereby warning the staff to stop moving the cargo, thereby avoiding the cargo tipping over and the elevator equipment being damaged by a large impact.

[0049] like Figure 1 and 3 As shown; the buffer mechanism 4 includes a sleeve 41 and an insertion rod 42, the insertion rod 42 is inserted into the sleeve 41 and fixedly connected to an adapted movable block 43, a first spring 44 is fixed to one side wall of the movable block 43, the outer end of the first spring 44 is fixedly connected to the inner wall of the sleeve 41, one end of the sleeve 41 is fixedly connected to the fixed plate 31, and one end of the insertion rod 42 is fixedly connected to the corresponding position of the movable plate 32;

[0050] When the movable plate 32 is impacted, the movable plate 32 drives the insertion rod 42 to push the movable block 43, thereby compressing the first spring 44, thereby achieving a buffering effect;

[0051] like Figure 1 and 4 As shown; a gap 21 is provided on the ground 2 near the elevator car, a carrier plate 22 is provided in the gap 21, a limit chute 23 is provided at the bottom of the inner cavity of the gap 21, an adaptive limit slider 24 is inserted into the inner cavity of the limit chute 23, a second pressure switch 27 is embedded in the top of the limit slider 24, the top of the second pressure switch 27 is fixedly connected to the bottom of the carrier plate 22, an electromagnet 26 is fixed to the end of the inner cavity of the limit chute 23 away from the car, a magnet block is fixedly embedded on one side wall of the limit slider 24 near the electromagnet 26, a second spring 25 is fixed to the other side wall of the limit slider 24, and the outer end of the second spring 25 is fixedly connected to the inner wall of the limit chute 23;

[0052] The second spring 25 drives the carrier plate 22 to reset, so that when the rear moving wheel moves onto the carrier plate 22 again, it will push the carrier plate 22 to fit the car, thereby ensuring that the transport device moves stably and is not stuck, thereby saving manpower, reducing the labor intensity of the staff, and avoiding the occurrence of cargo tipping.

[0053] Furthermore, the top of the carrier plate 22 is provided with anti-skid grooves, which can prevent the transport equipment from sliding.

[0054] The implementation principle of the wide-door elevator with a protective structure of the present application is as follows: in actual use, when the equipment for transporting goods moves into the elevator, it will be protected by the protective mechanism 3, which can guide the transporting equipment and the goods, thereby avoiding impact on the elevator door 11, the floor door 12 and the car door, which may cause damage to the elevator, thereby achieving a good protective limiting effect. When the goods transporting equipment and the goods enter the elevator, the movable plate 32 can limit and protect the transporting equipment. At the same time, when the movable plate 32 is impacted, the buffer mechanism 4 will be used for buffering. During the buffering process, the reverse internal force will be given, thereby driving the transporting equipment to move, thereby achieving a guiding effect, ensuring that the transporting equipment accurately enters the elevator, avoiding impact and damage to the elevator. When the movable plate 32 limits and guides the goods transporting equipment and is impacted, the buffer mechanism 4 can play a good buffering effect. When the goods are large and difficult to enter, and are continuously pushed with force, the movable plate 32 will continue to move, thereby giving a certain force to the first pressure switch 35 , thereby can start the alarm 13 to sound an alarm, thereby warning the staff to stop moving the goods, avoid the goods tipping over and the elevator equipment being damaged by a large impact. When the transport equipment enters the car, when the moving wheel on the front side of the transport equipment moves to the surface of the carrier plate 22, a certain pressure is applied to the second pressure switch 27, thereby starting the electromagnet 26 to generate a thrust on the magnet block on the side wall of the limit slider 24, thereby pushing the limit slider 24 to move in the limit slide groove 23, so that the carrier plate 22 moves and fits against the car, so that the moving wheels of the transport equipment will not get stuck when entering the car. At the same time, after the front moving wheels enter the car, the carrier plate 22 is not pressed, the electromagnet 26 is powered off, and under the action of the second spring 25, the carrier plate 22 is driven to reset, so that when the rear moving wheels move onto the carrier plate 22 again, the carrier plate 22 is pushed to fit against the car again, thereby ensuring that the transport equipment moves stably and is not stuck, thereby saving manpower, reducing the labor intensity of the staff, and avoiding the situation of cargo tipping over.
