Description

Adjustable water tank counterweight device for safety lock detection equipment

technical field

The invention relates to a safety lock detection device, in particular to an adjustable water tank counterweight device used for the safety lock detection device.

Background technique

The safety lock widely used in construction projects is an important safety component of the hanging platform for high-altitude operations. It must be used within the valid calibration period and must be calibrated once a year. As people pay more and more attention to safety technology, more and more problems are exposed in safety lock detection technology, and the demand for efficient and scientific safety lock detection equipment is increasingly strong. When using safety lock detection equipment to detect different types of safety locks, it is necessary to change the size of the counterweight frequently. At present, the existing safety lock detection equipment in China mainly uses counterweight iron to simulate the load of the suspension basket. In actual use, there are problems such as long time for counterweight adjustment, complicated manual operation, and high labor intensity, resulting in low utilization of the detection equipment.

Contents of the invention

In order to solve the above problems, the present invention provides a convenient way for adjusting the counterweight of the safety lock detection device by using the water tank system as the counterweight of the safety lock detection device.

The technical solution adopted by the present invention is: the adjustable water tank counterweight device of the safety lock detection equipment, including a water tank, a water storage tank, a water tank joint, and a protective rope, and four roller frames with rollers are installed on both sides of the water tank, and the rollers Roll along the raceway on the stand column; the water reservoir is installed with an inlet pump and a return pump, and communicates with the water tank through the inlet pipe and the return pipe; the water tank joint and the platform joint are connected by an adapter plate and two One end of the protective rope is connected to the lugs on both sides of the water tank, and the other end is connected to the support on the side of the stand column through a spring.

The beneficial effects of the present invention are: 1. During the detection process, the technical requirements of different counterweights can be easily realized by changing the weight of the water tank, which improves the utilization rate of the detection equipment; 2. It can be used under various working conditions. Realize the smooth operation of the counterweight of the water tank; 3. When the counterweight of the operating water tank suddenly falls, there are good buffer protection measures.

detailed description

The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

As shown in Fig. 1, Fig. 2 and Fig. 3, the water tank 4 used as the counterweight of the detection equipment is positioned between two bench columns 10, and four roller frames 2 with rollers 16 are respectively equipped on both sides of the water tank 4, and the rollers 16 It is connected with the roller frame 2 through the bolt 3. When the water tank moves up and down, the raceways 7 installed on the front and rear sides of the two columns 10 can limit the horizontal swing of the water tank 4 through the constraints of the rollers 16 .

The center of gravity position on the upper surface of the water tank 4 is equipped with a water tank joint 15, and the corresponding position on the suspension platform 11 is provided with a platform joint 12, and the platform joint 12 and the water tank joint 15 are connected by an adapter plate 13. When the detection equipment starts the lifting wire rope, the suspension platform 11 rotates around the rotating shaft 25, and the platform joint 12 on it also moves in an arc around the rotating shaft 25; because the water tank 4 can only move up and down in a straight line under the constraint of the roller 16 , between the water tank joint 15 and the platform joint 12, through the connection of the adapter plate 13 and the two pin shafts 14, the connection of the water tank 4 and the suspension platform 11, which are two parts with different motion paths, can be realized.

A water inlet pump 20 and a return water pump 22 are installed on the reservoir 21 below the suspension platform 11. The water inlet pump 20 is used to extract the water in the reservoir 21 and inject water into the water tank 4 through the water inlet pipe 23. The return water pump 22 passes through The water return pipe 24 connected thereto is used to draw the water in the water tank 4 and inject it into the water storage tank 21 . Just can change the weight of water tank 4 conveniently by changing the water level in the water tank 4, realize the technical requirement of different counterweight. During the testing process, the procedure of adjusting the weight of the water tank can be arranged at the same time as the disassembly and assembly of the safety valve, thus improving the utilization rate of the testing equipment.

A liquid level gauge 19 is installed on the water tank 4 to collect and indicate water level information, and the total weight of the water tank 4 is obtained through software conversion. When the weight of the water tank 4 needs to be changed, the start or stop of the water inlet pump 20 and the return pump 22 can be controlled by computer software after setting the required counterweight weight, and the system will automatically complete the adjustment work of the counterweight.

The displacement sensor 17 installed on the stand column 10 links to each other with the wiring board 18 installed on the roller frame 2 on the corresponding side of the water tank 4, and can collect relative vertical movement information of the relative stand column 10 of the water tank 4 .

The lifting lugs 5 on both sides of the water tank 4 are connected with a protective rope 6, and the other end of the protective rope 6 is connected to the support 8 positioned at the side of the stand column 10 through a spring 9. When the water tank 4 simulates a sudden fall, the shock absorber 1 installed on the bottom surface of the protective rope 6 and the water tank 4 can play a role of buffer protection.

The above description is used to illustrate the present invention, but not to limit the scope of the present invention. On the premise of not departing from the technical principle of the present invention, some modifications and changes can be made in the present invention, and these modifications and changes are also considered as the protection scope of the present invention.
