Description

Technical Field

[0001] This utility model relates to the field of elevator inspection technology, and in particular to a high-safety elevator inspection loading device. Background Technology

[0002] When conducting elevator traction and braking performance checks, speed governor-safety gear linkage tests, etc., the car needs to operate under different load conditions such as 40%, 50%, 100%, or 120% of the rated load. When loading the elevator for inspection, a convenient and controllable weight device is needed. Currently, the inspection loading device uses counterweights, weights, or water tanks in the inspection device to increase the weight. Among these, using counterweights is very inconvenient to handle and load, and the workload is high. Since counterweights are inconvenient and not precise enough, water is used as a substitute.

[0003] In the prior art, such as Chinese Patent No. CN220976174U, there is an elevator inspection loading device, which relates to the field of elevator inspection equipment technology. It includes a transparent water tank, with a mounting frame fixedly connected to the bottom of the transparent water tank. The bottom of the mounting frame is equipped with a stabilizing mechanism, and the top right side of the mounting frame is equipped with a portable mechanism. This utility model adds certain limiting and stabilizing measures to ensure the stability of the moving trolley and water tank inside the elevator, avoiding instability and preventing the water tank from shifting and colliding with the elevator, thus reducing the risk of collision damage between the water tank and the elevator.

[0004] While the above-mentioned solution has the advantages mentioned above, it also has disadvantages. Although it can achieve this by using a base, anti-slip plate, motor controller, power supply box, power supply, servo motor, screw, lifting frame, mounting plate, casters, opening, limit rod, and baffle to allow the casters to retract into the base and the bottom of the base to contact the bottom of the elevator's inner wall, and by using an anti-slip plate to increase the base's anti-slip properties and prevent it from sliding inside the elevator, thus increasing the stability of the transparent water tank inside the elevator, the device requires a motor controller, power supply box, power supply, and servo motor. This not only increases the overall production cost of the device but also may cause malfunctions during elevator inspection loading, where the casters may retract into the base, preventing the device from being moved out of the elevator and thus affecting the efficiency of elevator inspection loading. Utility Model Content

[0005] The purpose of this invention is to address the problems in existing technologies. While existing devices can achieve this by using a base, anti-slip plate, motor controller, power supply box, power supply, servo motor, screw, lifting frame, mounting plate, moving wheels, opening, limit rod, and baffle to retract the moving wheels into the base and ensure the bottom of the base contacts the bottom of the elevator's inner wall, and by using an anti-slip plate to increase the base's anti-slip properties and prevent it from sliding inside the elevator, thus increasing the stability of the transparent water tank inside the elevator, these devices require a motor controller, power supply box, power supply, and servo motor. This not only increases the overall production cost of the device but also carries the risk of malfunctions during elevator inspection loading, where the moving wheels may retract into the base, preventing the device from being moved out of the elevator and thus affecting the efficiency of elevator inspection loading.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a high-safety elevator inspection loading device, comprising: a car body, and further comprising:

Two limiting holes are opened on one side of the hollow strip. A limiting rod is slidably connected to one side of the U-shaped block. One end of the limiting rod is slidably connected inside one of the limiting holes. A sliding rod is slidably connected inside the hollow strip. An L-shaped strip is fixedly connected to the top of the sliding rod. Multiple limiting holes are equidistantly opened on one side of the sliding rod. A limiting rod is slidably connected to the other side of the hollow strip near the top. One end of the limiting rod is slidably connected inside one of the limiting holes.

[0008] Preferably, a limiting spring is provided on the outer surface of the limiting rod, and the limiting spring is fixedly connected to the U-shaped block and the limiting rod respectively.

[0009] Preferably, a second limiting spring is provided on the outer surface of the second limiting rod, and the second limiting spring is fixedly connected to the second limiting rod and the hollow strip respectively.

[0011] Preferably, two U-shaped blocks are symmetrically fixedly connected to the top of the vehicle body. Fixed rods are fixedly connected to the opposite side of the two arms of the U-shaped blocks. Push handles are rotatably connected to the outer surfaces of the two fixed rods. Elastic sponge sleeves are fixedly connected to the outer surfaces of the push handles.

[0012] Preferably, the push handle has multiple adjustment holes arranged in a circular array on opposite sides near the bottom, and one side of the U-shaped block is threaded with a screw, one end of which is slidably connected inside one of the adjustment holes.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] 1. This utility model allows the hollow strip to be released from its restriction by pulling the first limiting rod outward by hand, keeping the hollow strip horizontal. The hollow strip is then re-restricted. Next, the sliding rod is released from its restriction by pulling the second limiting rod outward by hand. This allows the sliding rod to move outward along the interior of the hollow strip, causing the rubber pad to adhere to the inside of the elevator car. The sliding rod is then re-restricted. Finally, by turning the crank handle by hand, the two adjacent U-shaped blocks are moved away from each other, causing the rubber pad to adhere to the right-angle position in the elevator car, thus providing stable support for the device. This eliminates the need for additional electrical equipment, reducing production costs and preventing electrical equipment malfunctions that could prevent the device from being removed from the elevator car, thereby improving the efficiency of elevator inspection and loading.

[0017] 2. In this utility model, by manually rotating the screw, it is disengaged from the interior of one of the adjustment holes, thus releasing the limitation on the push handle. At this time, the push handle can be rotated at an appropriate angle around the outer surface of the second fixing rod, and then the screw is rotated in the opposite direction to insert it into the interior of the other adjustment hole, thus limiting the push handle. This not only allows the elastic sponge sleeve to be adjusted to a suitable height, making it convenient for the user to push the device, but also allows the push handle to be moved closer to the water tank around the second fixing rod for storage, thereby reducing the space occupied by the device.

[0024] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

However, the present invention may also be implemented in other ways than those described herein, and therefore the present invention is not limited to the specific embodiments disclosed in the following specification.

[0026] Examples, such as Figure 1-4As shown, this utility model provides a high-safety elevator inspection loading device, including: a car body 1, and a water tank 101 fixedly connected to the top of the car body 1. A strip frame 2 is fixedly connected to opposite sides of the car body 1. A bidirectional screw rod 201 is rotatably connected to opposite sides of the inner wall of the strip frame 2. Two U-shaped blocks 203 are symmetrically threaded onto the outer surface of the bidirectional screw rod 201. A fixing rod 205 is fixedly connected to opposite sides of the two arms of the U-shaped blocks 203. A hollow strip 204 is rotatably connected to the outer surface of the fixing rod 205. A hollow strip 204 is rotatably connected to the outer surface of the hollow strip 204. Two limiting holes 208 are provided on the side. A limiting rod 206 is slidably connected to one side of the U-shaped block 203. One end of the limiting rod 206 is slidably connected inside one of the limiting holes 208. A sliding rod 209 is slidably connected inside the hollow strip 204. An L-shaped strip 213 is fixedly connected to the top of the sliding rod 209. Multiple limiting holes 210 are equidistantly provided on one side of the sliding rod 209. A limiting rod 211 is slidably connected to the other side of the hollow strip 204 near the top. One end of the limiting rod 211 is slidably connected inside one of the limiting holes 210.

[0027] Furthermore, such as Figure 1-4 As shown, a limiting spring 207 is provided on the outer surface of the limiting rod 206. The limiting spring 207 is fixedly connected to the U-shaped block 203 and the limiting rod 206 respectively. Under the reset force of the limiting spring 207, the limiting rod 206 can be inserted into the limiting hole 208 to limit the hollow strip 204.

[0028] Furthermore, such as Figure 1-4 As shown, a limiting spring 212 is provided on the outer surface of the limiting rod 211. The limiting spring 212 is fixedly connected to the limiting rod 211 and the hollow strip 204 respectively. Under the reset force of the limiting spring 212, the limiting rod 211 can be inserted into the interior of the limiting hole 210 to limit the slide rod 209.

[0029] Furthermore, such as Figure 1-4 As shown, a rubber pad 214 is fixedly connected to the right angle of the L-shaped strip 213, and a reinforcing rib is fixedly connected to the right angle of the slide rod 209 and the L-shaped strip 213. A crank handle 202 is fixedly connected to one end of the bidirectional screw rod 201. The outer surfaces of the two U-shaped blocks 203 are symmetrically slidably connected to the inside of the strip frame 2. The rubber pad 214 is used to avoid damage to the elevator car. The reinforcing rib is used to increase the firmness of the connection between the slide rod 209 and the L-shaped strip 213. The crank handle 202 is used to facilitate the rotation of the bidirectional screw rod 201.

[0030] Furthermore, such as Figure 1-4As shown, two U-shaped blocks 3 are symmetrically fixedly connected to the top of the vehicle body 1. Fixed rods 304 are fixedly connected to the opposite side of the two arms of the U-shaped blocks 3. Push handles 301 are rotatably connected to the outer surfaces of the two fixed rods 304. Elastic sponge sleeves 302 are fixedly connected to the outer surfaces of the push handles 301. With the above arrangement, the push handles 301 can rotate around the outer surfaces of the fixed rods 304, and the height of the elastic sponge sleeves 302 can be adjusted appropriately. The elastic sponge sleeves 302 increase the comfort of the user's hands.

[0031] Furthermore, such as Figure 1-4 As shown, the push handle 301 has multiple adjustment holes 303 arranged in a circular array on the opposite side near the bottom. A screw 305 is threadedly connected to one side of the U-shaped block 3. One end of the screw 305 is slidably connected to the inside of one of the adjustment holes 303. By rotating the screw 305, it can be inserted into the adjustment hole 303, which can limit the push handle 301.

[0032] Furthermore, such as Figure 1-4 As shown, an inlet pipe 102 is fixedly connected to the top of the water tank 101, and a drain pipe 103 is fixedly connected to the side of the water tank 101 near the bottom. A valve is fixedly connected to the outer surface of the drain pipe 103. The inlet pipe 102, the water tank 101 and the drain pipe 103 are connected. Water is added into the water tank 101 through the inlet pipe 102. By opening the valve, the water inside the water tank 101 can be discharged through the drain pipe 103.

[0033] Furthermore, such as Figure 1-4 As shown, a float 104 is suspended from the top of the inner wall of the vehicle body 1 by a pull rope. A transparent window and scale lines are provided on the other side of the water tank 101. By setting the float 104, the surface tension of the water can be changed when the device moves, thereby reducing the sloshing of the water. The transparent window and scale lines make it easy to observe the water volume inside the water tank 101.

[0034] Working principle: In use, water is added to the water tank 101 through the inlet pipe 102, and the water level is observed through the transparent window and scale. Simultaneously, the float 104 floats on the water surface. The float 104 changes the surface tension of the water when the device is moved, thus reducing water sloshing. Then, by holding the elastic sponge sleeve 302 and pushing the push handle 301, the device is moved into the elevator car and placed as centrally as possible. Next, by pulling the limiting rod 206 outwards, it disengages from one of the limiting holes 208, releasing the limitation on the hollow strip 204. Simultaneously, the limiting rod 206 is stretched, allowing the hollow strip 204 to wrap around the fixed rod. Rotate the outer surface of 205 downwards to keep the hollow strip 204 horizontal. Then release the limiting rod 206, allowing it to be inserted into the other limiting hole 208 under the restoring force of the limiting spring 207, thus limiting the hollow strip 204. Next, pull the limiting rod 211 outwards by hand to disengage it from one of the limiting holes 210, releasing the limitation on the slide rod 209. Simultaneously, stretch the limiting spring 212, allowing the slide rod 209 to move outwards along the interior of the hollow strip 204, bringing the L-shaped strip 213 closer to the inner wall of the elevator car and causing the rubber pad 214 to adhere to the interior of the elevator car. Then release the limiting rod 211, allowing it to be inserted into the other limiting hole 208 under the restoring force of the limiting spring 207. Under the reset force of 212, it is inserted into another limiting hole 210 to limit the slide rod 209. Then, by manually turning the crank handle 202, it drives the bidirectional screw 201 to rotate. Then, under the action of the threaded connection between the bidirectional screw 201 and the U-shaped block 203, and with the cooperation of the inner wall of the strip frame 2 in limiting and guiding the U-shaped block 203, the two adjacent U-shaped blocks 203 can be moved away from each other. Simultaneously, the hollow strip 204, slide rod 209, L-shaped strip 213 and rubber pad 214 are moved towards the right angle of the elevator car, so that the rubber pad 214 fits against the right angle position of the elevator car, thus providing stable support for the device and preventing the device from sliding. This eliminates the need for Adding electrical equipment reduces the production cost of this device and prevents malfunctions that could prevent it from being removed from the elevator car, thus improving the efficiency of elevator loading inspection. When the device is not needed, it can be operated in reverse. By manually turning the crank 202 in the opposite direction, the two U-shaped blocks 203 can be moved towards the center along the outer surface of the bidirectional lead screw 201. Then, by retracting the slide bar 209 into the hollow bar 204 and limiting it with the second limiting rod 211, and then by rotating the hollow bar 204 to a vertical position and limiting it with the first limiting rod 206, the hollow bar 204, slide bar 209, L-shaped bar 213, and rubber pad 214 can be stored. Figure 1As shown, by manually rotating the screw 305, it is disengaged from the interior of one of the adjustment holes 303, thus releasing the restriction on the push handle 301. At this time, the push handle 301 can be rotated at an appropriate angle around the outer surface of the second fixing rod 304, and then the screw 305 can be rotated in the opposite direction to insert it into the interior of the other adjustment hole 303, thus restricting the push handle 301. This not only allows the elastic sponge sleeve 302 to be adjusted to a suitable height, making it convenient for the user to push the device, but also allows the push handle 301 to be moved closer to the water tank 101 around the second fixing rod 304 for storage, thereby reducing the space occupied by the device.
