A vehicle-mounted GPS-RTK surveying instrument installation device

Abstract

The present invention relates to the field of control cabinet wiring technology, and in particular to an installation device based on a vehicle-mounted GPS-RTK surveying instrument, which includes a mounting assembly, a clamping assembly arranged on the inner side of the mounting assembly, and a pushing assembly arranged on one side of the clamping assembly; a wiring unit, including a limiting assembly arranged on the outer side of the clamping assembly, a wiring assembly arranged on the inner side of the mounting assembly, and a locking assembly arranged on the lower side of the pushing assembly. The beneficial effect of the present invention is that only by pulling the control handle by the staff, the wiring is kept in a vertical state within a certain distance from the access device, preventing the wiring from being excessively pulled by its own weight, causing the wiring terminal to be damaged or the wiring to become loose after long-term use, and can also enable the wiring to be accurately connected to the device after clamping and limiting. The cooperation between the contact ring and the terminal board prevents the wiring terminal from being exposed outside the terminal box when not connected, reducing terminal wear. In addition, after the wiring is completed, the control handle can be stored and limited to prevent the control handle from being accidentally touched during the operation of the device, causing the wiring to be separated from the device and causing a malfunction.

[0035] Furthermore, the linkage assembly 202 includes a pushing rack 202a provided on one side of the pushing latch 201d, a transmission gear 202b meshing with the pushing rack 202a, a linkage rack 202c meshing with the transmission gear 202b, a second transmission ratchet 202d meshing with the inner side of the transmission gear 202b, a limiting rotating wheel 202e provided on one side of the second transmission ratchet 202d, a second limiting pawl 202f provided on one side of the second transmission ratchet 202d, a rotating pin 202g provided at one end of the second limiting pawl 202f, and a rotating pin 202g provided on the linkage rack 202c. The movable clamp 202h on one side, wherein the pushing rack 202a is fixedly connected to the pushing pin 201d, the second limit pawl 202f is hinged to the limit rotating wheel 202e, and the rotating pin 202g is fixedly connected to the second limit pawl 202f. The rotating pin 202g can lock the second limit pawl 202f, so that the second limit pawl 202f is in contact with the limit rotating wheel 202e, thereby releasing the limit on the second transmission ratchet 202d, so that the second transmission ratchet 202d and the transmission gear 202b can be reversed, and the linkage rack 202c is fixedly connected to the movable clamp 202h.

[0036] Preferably, the lifting rack 101b meshes with the lifting gear 101c when it rises to a certain height. The lifting gear 101c is limited by the first transmission ratchet 101d and can only rotate when the lifting rack 101b rises. A return spring is provided at the tail end of the first limit pawl 101e, so that the first limit pawl 101e always limits the first transmission ratchet 101d under normal circumstances; an opening is provided on one side of the mounting sleeve 103b, and the position of the opening corresponds to the position of the lifting gear 101c. The lifting gear 101c meshes with the lifting rack 101b through the opening; the mounting block 103c is sleeved with the mounting sleeve 103b, and a movable groove is provided on the inner side of the mounting sleeve 103b. The mounting block 103c is only moved when It can move within the range of the groove. The lower diameter of the mounting block 103c is larger than the upper diameter. The mounting block 103c is inserted into the inner side of the mounting clamp 103a, pushing the mounting claws 103g to both sides, and the mounting block 103c continues to move downward. The mounting claws 103g clamp the smaller diameter part of the upper side of the mounting block 103c inward; the positioning slot 201b is provided with a slot adapted to the moving claw 202h. When the connecting block 201a descends, it drives the positioning slot 201b to descend to a position horizontal with the moving claw 202h. When the moving claw 202h moves inward, it can pass through the installation port provided by the production command vehicle and be smoothly inserted into the positioning slot 201b. The lower end of the positioning slot 201b is inserted into the reserved groove for the installation position of the production command vehicle.

[0037] During use, when the vehicle-mounted GPS-RTK surveying instrument is installed, the staff will place the mounting clamp 103a on the installation position of the production command vehicle, and perform preliminary fixation by installing the clamping claw 103g, and further fix the equipment to the lifting mounting rod 101a. Furthermore, the staff will simultaneously insert the lifting mounting rod 101a, the mounting sleeve 103b, and the mounting block 103c into the inner side of the mounting clamp 103a. When the mounting sleeve 103b is inserted to the bottom, the mounting block 103c is completely stuck in the inner side of the mounting clamp 103a. At this time, the buffer spring 103d is compressed, and when the staff releases When the lifting installation rod 101a is opened, the buffer spring 103d loses pressure and stretches, and the buffer spring 103d pushes the lifting installation rod 101a upward, and the lifting installation rod 101a drives the limiting ring to move upward synchronously until the lifting rack 101b and the first transmission ratchet 101d begin to engage, and the compression spring 102c pushes the supporting foot 102a to slide outward into the limiting groove 103f. Further, the staff continues to pull the lifting installation rod 101a upward to the required height according to needs, and the supporting foot 102a follows the rising edge of the lifting installation rod 101a to support the slideway 103e to open outward. The angle at which the support legs 102a are opened is adapted to the height at which the mounting rod is raised. The higher the height of the lifting mounting rod 101a is raised, the greater the angle at which the support legs 102a are opened. At the same time, when the mounting block 103c moves downward and is embedded in the inner side of the mounting clamp 103a, the mounting block 103c pushes the connecting block 201a downward, and the connecting block 201a drives the linkage pushing rod 201c to rotate to both sides, so that the linkage pushing rod 201c pushes the pushing latch 201d, so that the pushing latch 201d drives the pushing rack 202a to synchronously enter the inner side of the mounting clamp 103a, and the pushing rack 202a and the transmission gear The wheel 202b is engaged, and the pushing rack 202a drives the transmission gear 202b to rotate through engagement. At the same time, the transmission gear 202b drives the second transmission ratchet 202d to rotate through engagement. The second limiting pawl 202f limits the transmission ratchet, so that the transmission gear 202b and the second transmission ratchet 202d can only rotate in one direction. The transmission gear 202b synchronously drives the linkage rack 202c to move in the opposite direction, and the linkage rack 202c drives the mobile clamp 202h to move synchronously in the same direction, so that the mobile clamp 202h moves in the opposite direction to clamp the installation place of the production command vehicle.

[0038] When the vehicle-mounted GPS-RTK surveying instrument is disassembled, the staff drives the second limit pawl 202f to rotate inwardly by rotating the pin 202g. When the second limit pawl 202f is in contact with the limit rotating wheel 202e, the staff will clamp the rotating pin 202g into the inner side of the limit groove 103f to fix the second limit pawl 202f. Further, the staff presses the first limit pawl 101e to release the limit of the first limit pawl 101e on the first transmission ratchet 101d. Further, the staff keeps pressing the first limit pawl 101e and pushes the lifting installation rod 101a downward. At the same time, the supporting foot 102a is synchronously retracted inwardly. When the supporting foot 102a is fully retracted, the lifting installation rod 101a returns to its initial position, and the lifting rack 101b leaves the first transmission ratchet 101d. At this time, the staff releases the first limit clamping claw, and further the staff continues to push the lifting installation rod 101a downward. The lifting and mounting rod 101a squeezes the buffer spring 103d. When the buffer spring 103d is squeezed to fully compressed, the bottom of the lifting and mounting rod 101a contacts the mounting block 103c, pushing the limit cards on both sides outward, further pulling out the mounting sleeve 103b upward, and removing the vehicle-mounted GPS-RTK measuring instrument. At the same time, the mounting block 103c rises and pulls the connecting block 201a to move upward, and the connecting block 201a drives the linkage pushing rod 201c to rotate in the opposite direction, driving the pushing latch 201d to move inward and leave the inner side of the mounting clamp 103a. At the same time, the pushing latch 201d drives the pushing rack 202a to move synchronously, and the pushing rack 202a drives the transmission gear 202b to rotate in the opposite direction. The transmission gear 202b drives the linkage rack 202c to move in the opposite direction through engagement, and the linkage rack 202c drives the moving claw 202h to move outward, releasing the clamp on the production command vehicle, so that the entire mechanism is completely disassembled.

[0039] In summary, the present invention adjusts the installation height of the vehicle-mounted GPS-RTK measuring instrument by lifting and lowering the lifting installation rod 101a, and limits it through the ratchet group to prevent the vehicle-mounted GPS-RTK measuring instrument from falling or deflecting during the movement of the production command vehicle. The positioning slot 201b restricts the push pin 201d and the clamping cooperation between the push pin 201d and the moving clamp 202h to ensure that the vehicle-mounted GPS-RTK measuring instrument can be fixed in both the vertical and horizontal directions, and can be locked horizontally after ensuring its vertical installation stability during the installation process, so that the vehicle-mounted GPS-RTK measuring instrument has dual installation guarantees.
