Description

Technical Field

[0001] The utility model relates to the field of general pre-inspection mechanisms for lifting equipment, in particular to a size pre-inspection device for lifting equipment. Background Technique

[0002] In the processes of installation and withdrawal in the coal mining face, there are many large-sized equipment lifted by the auxiliary shaft, and the frequency is high. The size specification of the auxiliary shaft cage will limit the maximum lifting size of the equipment. In this case, before each large piece is lowered, the ground foreman is responsible for measuring the length, width and height of the large piece to ensure the normal lifting of the auxiliary shaft. However, there are certain deviations in manual measurement. If the measurement is inaccurate, it is easy to affect the normal operation of the auxiliary shaft lifting equipment and even the work section. Especially, the manual measurement process is cumbersome and commonly uses equipment such as ladders for assistance, which affects work efficiency.

[0003] In the prior art, there are also frame devices for limiting the width and height of workpieces, but such devices cannot measure the length of the equipment. Even if such brackets are installed, manual measurement by staff is still required, and their applicability is limited. In response to the above problems, there is currently a lack of corresponding solutions. Content of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a size pre-inspection device for lifting equipment that can automatically detect the length, width and height of the equipment, is suitable for pre-inspection of frequent lifting of large-sized equipment, and is free of manual operation.

[0005] The equipment includes a track, and a pre-inspection trolley is slidably arranged on the track;

[0006] The pre-inspection trolley includes a vehicle body, a slewing mechanism, a slewing disc and track wheels. The track wheels are arranged at the lower part of the vehicle body. A slewing mechanism is arranged in the vehicle body, and the slewing mechanism is power-connected to the slewing disc. The slewing disc is rotatably arranged on the upper surface of the vehicle body;

[0007] Forward from the front of the pre-inspection trolley, a first measurement bracket, a second measurement bracket and a lifting bracket are sequentially arranged on both sides of the track;

[0008] Both the first measurement bracket and the second measurement bracket are in the form of U-shaped frames;

[0009] The implementation purpose is that while the first measurement bracket and the second measurement bracket play a role in height limitation, they respectively measure the length and width of the workpiece;

[0010] A hoisting mechanism is arranged in the lifting bracket. The hoisting mechanism is used to lift the equipment from the pre-inspection trolley to the pusher.

[0011] The achieved effect is that large equipment is placed on the turntable of the pre-inspection trolley. The height and width of the workpiece are pre-inspected through the first measuring bracket. When the trolley moves between the first measuring bracket and the second measuring bracket, the turntable rotates 90 degrees, and the length of the workpiece is pre-inspected using the second measuring bracket. After passing the inspection, the equipment is lifted from the pre-inspection trolley to the pusher by the overhead crane mechanism.

[0012] The beneficial effects of the present utility model are as follows: The present utility model solves the problem of imperfect workpiece detection system in the prior art, realizes the pre-inspection of the length, width and height of the equipment, is beneficial to transportation safety and reduces the labor intensity.

[0019] Referring to Figure 1 , Figure 2 , a lifting equipment size pre-inspection device according to the present utility model includes a rail 1, and a pre-inspection trolley 8 is slidably arranged on the rail 1;

[0020] The pre-inspection trolley 8 includes a vehicle body, a slewing mechanism, a turntable 81 and rail wheels. The rail wheels are arranged at the lower part of the vehicle body, and a slewing mechanism is arranged inside the vehicle body. The slewing mechanism is power-connected to the turntable 81, and the turntable 81 is rotatably arranged on the upper surface of the vehicle body;

[0021] In the forward direction from the head of the pre-inspection trolley 8, a first measuring bracket 5, a second measuring bracket 4 and a lifting bracket 2 are sequentially arranged on both sides of the rail 1;

[0022] The described first measuring bracket 5 and second measuring bracket 4 are both in the form of U-shaped frames;

[0023] The purpose of its implementation is that while the first measuring bracket 5 and the second measuring bracket 4 play a role in limiting height, they respectively measure the length and width of the workpiece;

[0024] A hoisting mechanism 3 is arranged inside the lifting bracket 2. The hoisting mechanism 3 is used to hoist the equipment from the pre-inspection trolley 8 to the pusher.

[0025] The achieved effect is that the large equipment is placed on the turntable 81 of the pre-inspection trolley 8, and the height and width of the workpiece are pre-inspected through the first measuring bracket 5; when the trolley travels between the first measuring bracket 5 and the second measuring bracket 4, the turntable 81 rotates 90 degrees, and the length of the workpiece is pre-inspected using the second measuring bracket 4. After meeting the standards, the hoisting mechanism 3 hoists the equipment from the pre-inspection trolley 8 to the pusher.

[0026] Furthermore, the described track 1 is a double-row I-beam rail, and the track wheels of the pre-inspection trolley 8 are arranged corresponding to the track 1.

[0027] The achieved effect is to ensure the smooth travel of the trolley.

[0028] Furthermore, the described slewing mechanism includes a motor 85 and a speed reducer 84. The motor 85 is power-connected to the speed reducer 84, the speed reducer 84 is power-connected to a first gear 83, the first gear 83 meshes with a second gear 82, and the second gear 82 is power-connected to the turntable 81.

[0029] The achieved effect is to ensure the smooth rotation stroke of the turntable 81.

[0030] Furthermore, the second measuring bracket 4 and the first measuring bracket 5 are of equal height, and the widths of the two brackets are respectively set corresponding to width limitation and length limitation.

[0031] The achieved effect is to respectively constrain and limit the length, width, and height of the equipment.

[0032] Furthermore, the width of the second measuring bracket 4 is greater than that of the first measuring bracket 5;

[0033] An infrared signal transmitter 7 is arranged on the vertical support rod of the second measuring bracket 4;

[0034] An extension arm is arranged on the vertical support rod of the first measuring bracket 5, and an infrared signal receiver 6 is arranged on the extension arm; and the infrared signal receiver 6 is signal-connected to an alarm device.

[0035] Preferably, multiple groups of the infrared signal transmitter 7 and the infrared signal receiver 6 are arranged opposite to each other.

[0036] The achieved effect is that when the trolley moves between the first measuring bracket 5 and the second measuring bracket 4, the rotary disk 81 rotates 90 degrees. If the rotating part blocks the signal between the infrared signal receiver 6 and the transmitter, it proves that the length of the workpiece is greater than the conveying size limit. And this can prevent the equipment from colliding with the bracket.
