Description

Technical Field

[0001] The present invention relates to the technical field of dynamic weighing, and particularly to a mounting bracket for a high-speed dynamic track weighing device. Background Art

[0002] Dynamic weighing technology refers to a method for measuring the weight of moving objects, which is widely used in many fields such as rail transit, non-site law enforcement on expressways, source overloading control, logistics sorting, sorting scales, etc. The market demand for related products is huge. A dynamic rail scale can weigh the weight of a train under certain vehicle speed limit conditions, and the metering speed is relatively high. The mainstream of train weighing adopts dynamic rail scale technology. After the detector and the machine base are installed on the track, they are completely fixedly arranged on the track, resulting in the need to remove the entire section of the track where the installation problem, such as installation deviation, is found. The installation and disassembly work is complex. When the detection device fails, it is necessary to remove the entire mounting base and then reinstall the track part, which is time-consuming and laborious. Summary of the Invention

[0003] The purpose of the present invention is to provide a mounting bracket for a high-speed dynamic track weighing device to overcome the above-mentioned defects in the prior art.

[0004] An installation frame of a high-speed dynamic track weighing device according to the present invention includes a track. There are two symmetrically placed boxes on the left and right on the track. The placed boxes are abutted and arranged at the lower end of the track. Two symmetrically placed sliding grooves are opened at the upper end of the track. Sliders are slidably connected to both of the two sliding grooves. Gravity detection mechanisms are provided at the mutually approaching ends of the two sliders. The gravity detection mechanisms are connected to a data acquisition card. Positioning plates and baffles are respectively connected to the front and rear end faces of the placed box. The placed box is slidably connected to the positioning plate. The positioning plate is located at the rear end of the baffle. A threaded fixing member is connected between the positioning plate and the baffle. The threaded fixing member penetrates through the placed box. The threaded fixing member is fixed to the baffle by threaded connection and is used to clamp the slider. Rotating blocks are connected to both of the two sliders. Threaded grooves are provided on the outer circumferences of the rotating blocks. Rotating sleeves are connected to the outer circumferences of the rotating blocks and at the mutually remote ends of the two sliders. The slider is threadedly connected to the threaded groove. A fixing sleeve is threadedly connected to the outer circumference of the rotating sleeve. A push spring is connected between the rotating sleeve and the fixing sleeve. The push spring is fixedly connected to the rotating sleeve and abuts against the fixing sleeve. Guide sliding cylinders are fixedly provided at the mutually approaching ends of the two rotating blocks. A sliding cavity is opened in each of the guide sliding cylinders. An expansion link is slidably connected to each of the guide sliding cylinders. A push spring is connected between the guide sliding cylinder and the expansion link. Fixing rings are fixedly provided at the mutually approaching ends of the left and right groups of expansion links. Shock-absorbing pads are connected to the mutually approaching ends of the two fixing rings. The gravity detection mechanism is arranged in the fixing ring. The gravity detection mechanism can abut against the left and right side walls of the track. Sliding cavities are opened in both of the two placed boxes. Sliding pieces are hinged to the upper side walls of the two sliding cavities. The lower end face of the sliding piece abuts against the upper end face of the lower part of the track. A rotating groove is communicated and opened on the upper side wall of the sliding cavity. A power motor is fixedly provided in the rotating groove. A rotating rod is power-connected to the power motor. Two rotating wheels distributed front and rear are fixedly provided on the outer circumference of the rotating rod. The peripheral surface of the rotating wheel abuts against the upper end face of the lower part of the track. A stabilizing plate is fixedly provided in the rotating groove. The stabilizing plate is rotatably connected to the rotating rod. A sliding groove is communicated and opened on the lower side wall of the sliding cavity. A sliding block capable of sliding up and down is provided in the sliding groove. A rolling groove is opened in the sliding block. Rollers are connected to both of the two rolling grooves. The upper end part of the roller is rotatably connected to a sliding sleeve. The sliding sleeve is in close contact with the track. Oblique patterns are provided on the outer circumference of the rotating wheel. An electromagnetic self-locking mechanism is provided on the stabilizing plate. The lower part of the track and the upper side wall of the sliding cavity are both inclined.

[0005] The beneficial effects of the present invention are:

[0006] After installing the track, by controlling the two placement boxes to approach each other, the placement boxes slide upward along the inclined surface, losing the contact with the ground, resulting in a reduction in the friction force at the sliding sleeve, so that the sliding sleeve can slide back and forth at the lower end of the track;

[0007] Through the contact of the rollers with the ground, the position of the placement box can be adjusted after installation, thus improving the practicality;

[0008] By removing the threaded connection between the threaded fastener and the baffle, the slider can be taken out from the placement box, facilitating the replacement of the gravity detection mechanism at the rotating block;

[0009] The rotating block changes its position through the rotating sleeve, fixed sleeve and push spring, which is convenient for adjustment during the change of the position of the placement box, maintaining the contact between the gravity detection mechanism and the track and keeping the detection effect.

The stabilizing plate 38 is rotatably connected to the rotating rod 29. A sliding groove 37 is communicated and opened on the lower side wall of the sliding cavity 35. A sliding block 31 capable of sliding up and down is provided in the sliding groove 37. A rolling groove 34 is opened in the sliding block 31. A roller 32 is connected to each of the two rolling grooves 34. The upper end part of the roller 32 is rotatably connected to a sliding sleeve. The sliding sleeve is in close contact with the track 10. Oblique patterns are provided on the outer periphery of the rotating wheel 28. An electromagnetic self-locking mechanism is provided on the stabilizing plate 38. The lower part of the track 10 and the upper side wall of the sliding cavity 35 are both inclined;

[0025] Connect two placement bins 11 distributed left and right to the positioning plate 12. The placement bins 11 can slide left and right on the positioning plate 12. At the upper end of the placement bin 11, a slider 14 is slidably inserted through a sliding groove 25 on the placement bin 11, and a baffle 13 connected by threads is fixed through a threaded fixing member 33. The baffle 13 is located at the front end part of the slider 14 and abuts against the slider 14. The positioning plate 12 and the slider 14 clamp the slider 14 close to each other. Place the placement bin 11 and the positioning plate 12 on the installation surface so that the lower ends of the placement bin 11 and the positioning plate 12 abut against the installation surface. Place the placement bin 11, the positioning plate 12, and the slider 14 evenly front and back. The lower end of the track 10 abuts against the sliding sleeve on the roller 32. The roller 32 is rotatably connected to the sliding block 31. The two placement bins 11 on the left and right slide left and right on the positioning plate 12. The lower end part of the track 10 is placed downward and inserted into the sliding cavity 35 provided on the two placement bins 11, as Figure 1 shown;

[0026] The sliding piece 30, the rotating wheel 28 abut against the lower end part of the track 10. When moving, the power motor 27 is powered on to work, and the electromagnetic self-locking mechanism on the stabilizing plate 38 is powered on. The stabilizing plate 38 loses the self-locking restriction on the rotating rod 29, enabling the rotating rod 29 to rotate. Drive the rotating rod 29 fixedly connected to the power motor 27 to rotate, so that the rotating wheel 28 fixedly connected to the rotating rod 29 rotates. Through the abutment of the left and right groups of rotating wheels 28 and the track 10, drive the two placement bins 11 on the left and right to approach each other. The sliding piece 30 guides the sliding. The lower end part of the track 10 and the upper side wall of the sliding cavity 35 are both inclined. Through the abutment of the inclined part, when the two placement bins 11 approach each other, the placement bin 11 slides upward. The roller 32 and the sliding block 31 connecting the roller 32 remain in contact through the abutment of the track 10. The lower end of the roller 32 abuts against the installation surface, and the lower end of the placement bin 11 loses the abutment with the ground, so that the roller 32 can roll on the abutting ground. By pushing the placement bin 11, the roller 32 rotates on the ground, and the sliding sleeve slides on the lower end of the track 10 to adjust the position of the placement bin 11. In the energized state of the electromagnetic self-locking mechanism at the stabilizing plate 38, through the oblique patterns on the outer circumference of the rotating wheel 28, the two placement bins 11 can move in the front-back direction when approaching each other. The placement bin 11 can also change its front-back position by manual pushing;

[0027] Two rotating blocks 15 are inserted into the slider 14 close to each other and are threadedly connected to the threaded grooves 16 on the rotating blocks 15 through the internal threads of the slider 14, so that the rotating blocks 15 are arranged on the slider 14. The guide sliding cylinder 20 and the telescopic rod 22 connected to the rotating blocks 15 push the fixed ring 23 to move towards the rail 10 under the spring thrust of the push spring 21, so that the shock-absorbing pad 24 abuts against the rail 10. The gravity detection mechanism 36 abuts against the rail 10 through the fixed connection with the fixed ring 23 to detect the weight of the transport vehicle when passing through the rail 10. A rotating sleeve 17 is placed at the outer end extension of the rotating block 15. The rotating sleeve 17 is in threaded fit with the fixed sleeve 18 and is screwed onto the rotating block 15. The fixed sleeve 18 abuts against the slider 14 through the spring force of the push spring 19. When the placement box 11 moves, the elastic force of the push spring 21 changes. By screwing the rotating sleeve 17 into a certain depth and through the fixed connection between the rotating sleeve 17 and the rotating block 15, the rotating block 15 is driven to rotate, thereby controlling the position of the rotating block 15 so that the gravity detection mechanism 36 remains in contact with the rail 10.
