AI Technical Summary
When the elevator is stopped for loading and unloading, due to its own weight and heavy load, it is difficult to keep the body stable by relying on only four wheels. This can easily cause wheel slippage and instability, leading to overturning and tipping over, which poses a safety hazard.
An anti-slip support device was designed, comprising a base, a fixed inclined block, a movable inclined block, a screw, and a nut sleeve. Through the cooperation of the screw and the nut sleeve, the movable inclined block can move back and forth, increasing the contact area between the wheel and the ground, increasing friction, providing stable support, and preventing tipping.
It effectively increases the friction between the elevator and the ground, preventing tipping and ensuring the safety of equipment and personnel.

Description
Technical Field
[0001] This utility model relates to elevators, and in particular to an anti-slip support device for elevators. Background Technology
[0002] When the elevator is stopped for loading and unloading, due to its own weight and heavy load, it is difficult to keep the machine stable by relying on only four wheels. This can easily cause wheel slippage and machine instability, leading to overturning and tipping, which can endanger the equipment and personal safety. Summary of the Invention
[0003] The purpose of this utility model is to provide an anti-slip support device for elevators to prevent the elevator from tipping over when it stops to load or unload goods.
[0004] The anti-slip support device for a lift provided by this utility model includes a base, a fixed inclined block, a movable inclined block, a screw, and a nut sleeve. The base is "п"-shaped (i.e., one end of the base is open and the other end is closed). The width of the inclined surfaces of the fixed and movable inclined blocks is slightly greater than the thickness of the lift wheel. The fixed inclined block is installed at the open end of the base, and the movable inclined block is located at the closed end of the base. The inclined surfaces of the fixed and movable inclined blocks face each other. The movable inclined block can slide along both sides of the base. The high end of the movable inclined block is rotatably connected to the inner end of the screw through an inner groove located at its center (i.e., this end of the screw can rotate radially in the inner groove, but cannot move axially). The nut sleeve is fixedly installed on the crossbeam at the closed end of the base and is connected to the screw with a trapezoidal thread. The movable inclined block can be moved back and forth by turning the screw.
[0005] When the elevator stops for loading and unloading, the anti-slip support device of this invention can lift all four wheels off the ground.
[0006] It's like putting "anti-slip boots" on each of the four wheels, which effectively increases the contact area between the elevator and the ground. On the one hand, it increases the friction between the elevator and the ground, thus preventing slippage; on the other hand, it also provides support and stability to the elevator body, preventing it from tipping over when loading and unloading goods.

[0021] Combination Figure 1 and Figure 2 This utility model relates to an anti-slip support device for a lifting platform, comprising a base 1, a movable inclined block 5, a fixed inclined block 6, a screw 2, and a nut sleeve 3. The base 1 is as follows... Figure 3 As shown, the base is open at one end and closed at the other, forming a "п" shape. The cross-sections of both sides of the base are inverted "T" shapes. The center of the crossbeam at the closed end has a nut mounting hole 11, and the two sides of the open end each have threaded holes a12 that mate with screw b7. Figure 1 , Figure 4 , Figure 5 and Figure 6The movable inclined block 5 has an inclined surface width slightly greater than the thickness of the elevator wheel. The movable inclined block is located at the closed end of the base, with its inclined surface facing the open end of the base. The inclined block has U-shaped grooves on both sides that can slide along the sides of the base (e.g., ...). Figure 4 As shown), the high-end center of the inclined block has an inner groove 51 formed by a groove, which allows the inner end of the screw 2 (the end connected to the movable inclined block) to be axially limited and radially rotatable; combined with Figure 1 , Figure 7 , Figure 8 and Figure 9 The fixed inclined block 6 has the same inclined surface width as the movable inclined block, and has "U"-shaped grooves on both sides that can slide along the sides of the base (e.g., Figure 8 and Figure 9 As shown), there are threaded holes b61 on both sides of the groove that mate with screw b7. The inclined surface of the fixed inclined block is opposite to the inclined surface of the movable inclined block (as shown). Figure 1 As shown); the screw 2 is as follows Figure 11 As shown, its inner end has a circular convex cap, which is placed in the inner groove 51 of the movable inclined block 5 and can rotate in the inner groove, but cannot move axially; the nut sleeve 3 is as follows Figure 10 As shown, it is fixedly installed in the nut sleeve mounting hole 11 of the base by four screws a4 (as shown). Figure 1 and Figure 2 As shown), the nut sleeve and the screw are connected by a trapezoidal thread. The screw can be turned with a wrench, which drives the movable inclined block to move back and forth on the base.
[0022] Combination Figure 12 The operation and use method of the above-mentioned anti-slip support device for the elevator: When the elevator stops to load or unload goods, corresponding to the four
[0023] For each elevator wheel 8, take four anti-slip support devices. First, remove the fixed wedge block from the open end of each anti-slip support device. Insert the open end of the base into both sides of the wheel (because the width of the base is greater than the thickness of the wheel), and make the two sides of the base extend beyond the wheel. Re-fix the removed fixed wedge block to the open end of the base with screw b. Place the base on the ground and push it along the ground so that the inclined surface of the fixed wedge block is in close contact with the front end of the wheel. Then, use a wrench to tighten the screw, pushing the movable wedge block along the base towards the fixed wedge block until each wheel is lifted off the ground, so that the weight of the elevator body 9 is borne by the anti-slip support device. After loading and unloading, tighten the screw in the opposite direction to make the wheel land on the ground again. Then, remove the fixed wedge block, pull out the base, and reinstall the fixed wedge block on the base for the next use of the device.
[0024] The components of the anti-slip support device for the elevator of this utility model can be made of stainless steel, and reinforcing ribs can be provided below the bottom surface of the fixed inclined block and the movable inclined block.
