Description

Technical Field

[0001] This utility model belongs to the field of building construction testing equipment, specifically relating to a device for detecting the horizontal displacement of a building foundation pit. Background Technology

[0002] A horizontal displacement detector for a building foundation pit calculates horizontal displacement by measuring the borehole inclination angle. Horizontal displacement detectors typically mark half-meter intervals on the cable to allow workers to record data after lowering the cable to a certain length. Traditional detectors cannot lower the cable automatically, making data recording inconvenient, and cable winding is often loose and messy. While the horizontal displacement detection device disclosed in the existing utility model patent (CN219078781U) can effectively control the lower length of the cable, it cannot evenly wind the cable during winding. The uniformity of the cable winding on the reel requires manual control, making it very inconvenient to use. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model aims to provide a horizontal displacement detection device for building foundation pits. This device is simple and convenient to use. The control module can effectively control the lower length of the cable and can evenly and tightly wind the cable onto the reel during winding, thereby effectively avoiding problems such as loosening, tangling, and knotting of the cable after winding.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A horizontal displacement detection device for a building foundation pit includes a vehicle body with cable holes. A rotating shaft is horizontally mounted on the upper part of the vehicle body, and a cable reel is coaxially fixed on the rotating shaft. A cable organizer is installed below the cable reel inside the vehicle body, and a motor mounting cavity is located below the cable organizer. A drive motor is installed in the motor mounting cavity, and the drive shaft of the drive motor is connected to the upper rotating shaft and the cable organizer via a belt structure. A control module is also installed on the vehicle body, which controls the rotation of the drive motor to control the lower length of the cable. A cable pressing mechanism is also installed at the top of the vehicle body. The cable pressing mechanism includes a cable pressing roller and an elastic lifting assembly. The elastic lifting assembly is installed at the top of the vehicle body, and the cable pressing roller is horizontally mounted on the moving part of the elastic lifting assembly and tangent to the upper circumferential surface of the cable reel.

[0006] Preferably, the cable organizer includes a slide rod, a cable roller, and a movable block. The slide rod and the cable roller, which are arranged parallel to the rotating shaft, are horizontally installed in the vehicle body. The movable block is movably sleeved on the cable roller and slidably sleeved on the slide rod. A guide block is fixedly provided on the inner wall of the movable block. The guide block is slidably engaged with a bidirectional threaded groove provided on the outer circumference of the cable roller. The end of the cable roller is connected to the rotating shaft in a dynamic direction through a corresponding belt structure. A wire roller is installed above the movable block.

[0007] Preferably, a first pulley is coaxially mounted on the drive shaft of the drive motor, a second pulley and a third pulley are coaxially mounted on the rotating shaft, a fourth pulley is coaxially mounted on the end of the thread-sorting roller, a first belt is provided between the first pulley and the second pulley, and a second belt is provided between the third pulley and the fourth pulley.

[0008] Preferably, the elastic lifting assembly includes a lifting plate and a pressing plate arranged parallel to each other vertically. A screw is rotatably mounted on the top of the lifting plate, and the upper end of the screw is threaded through the top surface of the vehicle body, extends out of the vehicle body, and is fitted with a handle. A first limiting rod is vertically fixed to the top of the lifting plate, and the upper end of the first limiting rod moves upward through the top surface of the vehicle body and is fixed with a first limiting block. Multiple springs are vertically fixed between the pressing plate and the lifting plate. The pressure roller is installed below the pressing plate.

[0009] Preferably, a second limiting rod is vertically fixed to the top of the pressing plate, and a second limiting block is fixed to the upper end of the lifting plate that extends upward through the second limiting rod. A spring is sleeved on the second limiting rod, and the upper and lower ends of the spring abut against the lifting plate and the pressing plate, respectively.

[0010] Preferably, two pressure rollers are installed in parallel below the pressure plate, and the two pressure rollers are tangent to the upper circumferential surface of the winding reel.

[0011] Preferably, a handrail is installed on the right side of the vehicle body.

[0012] Preferably, an inspection door is provided on the left side of the vehicle body.

[0013] Preferably, heat dissipation holes are provided on the outer wall of the motor mounting cavity.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. After the cable enters the vehicle body through the cable hole, it first passes around the guide roller and then winds upward onto the reel. Under the limiting action of the slide rod, the moving block slides with the guide hole and the bidirectional threaded groove in the guide hole. Then, the rotation of the cable roller causes the moving block to move back and forth, which in turn drives the guide roller to move left and right back and forth. This can evenly wind the cable onto the reel, making the cable winding more uniform.

[0016] 2. In this application, when winding and organizing the cable, the worker rotates the handle to extend the screw downwards and the lifting plate falls until the two pressure rollers press against the surface of the cable on the winding reel. Under the cable organizing action of the cable organizer, the cable is evenly wound on the winding reel. As the thickness of the cable winding increases, the pressure rollers will squeeze the spring upwards. Under the action of the spring force, the cable winding can be made tighter.

[0017] 3. This application uses the cooperation of the first belt and the corresponding pulley to transmit the power of the drive motor to the shaft and the winding reel, and then uses the power transmission of the second belt to realize the power transmission of the winding roller, which has higher power transmission efficiency.

[0021] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of application of this utility model.

[0022] like Figure 1-3 As shown, this utility model proposes a horizontal displacement detection device for building foundation pits, including a vehicle body 1. A cable hole (not shown in the attached figure) is provided on the front side wall of the vehicle body 1. A rotating shaft 2 is horizontally mounted above the interior of the vehicle body 1. A cable reel 4 is coaxially fixed on the rotating shaft 2. A cable organizer is installed inside the vehicle body 1 below the cable reel 4. A motor mounting cavity 10 is provided inside the vehicle body 1 below the cable organizer. A drive motor 11 is installed inside the motor mounting cavity 10. Heat dissipation holes are provided on the outer wall of the motor mounting cavity 10 for heat dissipation and ventilation of the drive motor 11. The drive shaft of the drive motor 11 is connected to the rotating shaft 2 and the cable organizer via a belt structure. The cable organizer includes a sliding rod 32, a cable roller 31, and a moving block 33. The sliding rod 32 and the cable roller 31, arranged parallel to the rotating shaft 2, are horizontally mounted inside the vehicle body 1. The moving block 33 has a horizontally opening sleeve hole. The cable roller 31 is slidably fitted into the sleeve hole, and the moving block 33 is also horizontally slidably fitted onto the sliding rod 32. A guide block is fixedly provided on the inner wall of the sleeve hole, and the guide block is slidably engaged with the bidirectional threaded groove 310 provided on the outer circumferential surface of the thread roller 31. The sleeve engagement between the bidirectional threaded groove 310 and the moving block 33 to achieve the reciprocating movement of the moving block 33 is a common technical means in the prior art, and its principle will not be elaborated here.

[0023] After the cable enters the vehicle body 1 through the cable hole, it first passes around the guide roller 34 and then winds upward onto the winding reel 4. Under the limiting action of the slide rod 32, the moving block 33 slides with the guide hole in the guide hole and the bidirectional threaded groove 310. Then, when the cable roller 31 rotates, the moving block 33 moves back and forth, which in turn drives the guide roller 34 to move left and right back and forth. This can evenly wind the cable onto the winding reel 4, making the cable winding more uniform.

[0024] The end of the thread-training roller 31 is connected to the rotating shaft 2 via a corresponding belt structure; a guide roller 34 is mounted above the moving block 33. A first pulley 111 is coaxially mounted on the drive shaft of the drive motor 11, a second pulley 21 and a third pulley 22 are coaxially mounted on the rotating shaft 2, and a fourth pulley 311 is coaxially mounted at the end of the thread-training roller 31. A first belt is provided between the first pulley 111 and the second pulley 21, and a second belt is provided between the third pulley 22 and the fourth pulley 311. This application utilizes the cooperation of the first belt and the corresponding pulleys to transmit power from the drive motor 11 to the rotating shaft 2 and the winding reel 4, and then uses the power transmission of the second belt to realize the power transmission of the thread-training roller 31, resulting in higher power transmission efficiency.

[0025] A control module 13 is also installed on the vehicle body 1. The drive motor 11 is connected to the control module 13. The control module 13 controls the rotation of the drive motor 11 to control the lower length of the cable, ensuring that the lower length of the cable is exactly half a meter. This facilitates the timely recording of measurement data at the current position by the staff, thereby improving the efficiency of the staff. The control module 13 controls the number of rotations of the motor through software program to control the cable length, which is a common technical method in the prior art and will not be described in detail here.

[0026] A wire pressing mechanism is also installed on the top of the vehicle body 1. The wire pressing mechanism includes a wire pressing roller 5 and an elastic lifting assembly 6. The elastic lifting assembly 6 is installed on the top of the vehicle body 1, and the wire pressing roller 5 is horizontally installed on the moving part of the elastic lifting assembly 6 and tangent to the upper circumferential surface of the winding reel 4. The elastic lifting assembly 6 includes a lifting plate 64 and a pressing plate 61 arranged parallel to each other. A screw 66 is rotatably installed on the top of the lifting plate 64. The upper end of the screw 66 is threaded through the top surface of the vehicle body 1, extends out of the vehicle body 1, and is fitted with a handle 661. A first limiting rod 65 is vertically fixed to the top of the lifting plate 64. The upper end of the first limiting rod 65 moves upward through the top surface of the vehicle body 1 and is fixed with a first limiting block 651. The first limiting rod 65 can slide and limit the up and down movement of the lifting plate 64, and the first limiting block 651 can limit the movement length of the first limiting rod 65. A second limiting rod 62 is vertically fixed to the top of the pressing plate 61. The second limiting rod 62 extends movably through the lifting plate 64 and has a second limiting block 621 fixed to its upper end. The second limiting block 621 can limit the movement of the second limiting rod 62. A spring 63 is sleeved on the second limiting rod 62, and its upper and lower ends abut against the lifting plate 64 and the pressing plate 61, respectively. Two pressure rollers 5 are installed parallel to each other below the pressing plate 61, and the two pressure rollers 5 are tangent to the upper circumferential surface of the winding reel 4.

[0027] When winding and organizing the cable, the operator rotates the handle 661 to extend the screw 66 downwards, and at the same time, the lifting plate 64 falls until the two pressure rollers 5 press against the surface of the cable on the winding reel 4. Under the cable organizing action of the cable organizer, the cable is evenly wound on the winding reel 4. As the thickness of the cable winding increases, the pressure rollers 5 will squeeze the spring 63 upwards. Under the elastic force of the spring 63, the cable winding can be made tighter.

[0028] A handrail 12 is installed on the right side of the vehicle body 1 to facilitate the movement and transport of this device. An inspection door 14 is provided on the left side of the vehicle body 1, which can be opened to inspect and maintain the interior.

[0029] When using this invention for cable unwinding, the wire pressing mechanism does not contact the reel 4. The operator gently pulls the cable end at the cable hole, and with the control module 13 controlling the drive motor 11, the cable length is lowered precisely by half a meter, allowing the operator to record measurement data at the current position promptly. When winding the cable, the operator rotates the handle 661 to make the two wire pressing rollers 5 of the wire pressing mechanism abut against the reel 4. The drive motor 11 rotates in the opposite direction, causing the cable organizer and reel 4 to rotate, allowing the cable to be evenly and tightly wound onto the reel 4, making it very convenient to use.
