Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1 to 2, the drilling rack vehicle for the highway bridge support comprises a box-shaped carriage 1, wherein horizontal bearing rods 2 are respectively mounted at the tops of two opposite side surfaces of the carriage 1, the end part of each horizontal bearing rod 2 is connected with a limiting support 3, and a pulley 5 is mounted at the bottom of each horizontal bearing rod 2 between each limiting support 3 and the carriage 1 through a linear moving assembly 4;

the linear moving assembly 4 is fixedly connected with the horizontal bearing rod 2, the linear moving assembly 4 comprises two limiting plates 401, two sides of each limiting plate 401 are connected with the horizontal bearing rod 2 through connecting plates, through holes 402 are formed in the two limiting plates 401, two moving plates 403 penetrate between the two through holes 402, a horizontal partition plate 404 is mounted at the upper end of each moving plate 403, and each partition plate 404 is arranged above the corresponding limiting plate 401 at the upper end of each connecting plate;

a slider 405 is installed in a through hole 402 of the limiting plate 401 at the lower end of the connecting plate, the slider 405 is installed between the two moving plates 403, the lower end of the slider 405 is fixedly connected with the pulley 5 through a connecting rod, and the slider 405 slides between the two moving plates 403 so as to drive the pulley 5 to move in the horizontal direction.

This embodiment has improved on traditional U type rack car, design into E type opening with U type rack car, change traditional rack car unilateral atress into two side atress simultaneously, compare in the unilateral atress, two side atress of E type open-ended rack car are safer, reduce the risk of collapsing, traditional rack car does not set up the gyro wheel structure, if the position of rack car needs to be adjusted, can only rely on artifical the removal about, waste time and energy, be unfavorable for the whole progress of engineering, and traditional rack car needs four people to come the operation, personnel's configuration is too much, the resource has been wasted, only need three workman to operate the rack car in this embodiment, personnel's configuration has been optimized, make the whole engineering progress accelerate.

It should be added that the two moving plates 403 in this embodiment function to define the position of the pulley 5, and the top end surface of the limiting plate 401 is provided with a plurality of grooves 406 for accommodating the spacers 404, and the grooves 406 are the same as the spacers 404 in size, so that when the spacers 404 are placed in the grooves 406, the spacers 404 are fixed in the grooves 406;

since the worker is in the carriage 1 and the whole trolley is forced downward, when the partition 404 is placed in the groove 406, the force of the whole pulley 5 is mainly concentrated downward, and the moving plate 403 is forced in the left and right directions of the groove 406 so that the moving plate 403 is fixed.

In this embodiment, when the pulley 5 needs to be changed, one moving plate 403 slides to one side and is placed in one groove 406, and then one moving plate 403 is pulled upward and is pushed to move along the slider 405 to reach a preset position of the slider 405, and the partition is placed in a proper groove, so that the two moving plates 403 are attached to the slider 405, and the purpose that the moving plate 403 limits the position of the slider 405 is achieved.

Carriage 1 and horizontal bearing bar 2 pass through articulated elements 6 to be connected, and the lower extreme that is close to carriage 1's connecting plate articulates there is dimension steady board 7, and the one end that dimension steady board 7 kept away from the connecting plate articulates on the connecting rod between carriage 1 and horizontal bearing bar 2.

It should be particularly noted that, because the actual construction environment is variable, height differences may exist on two sides of a bridge, and the two sides of a conventional rack vehicle are fixedly connected, if there is a large height difference on the two sides of the bridge, the rack vehicle may have a condition that one side is high and the other side is low, and may not enter a crack, which affects the operation of workers and people, the function of the stabilizer plate 7 in the embodiment in combination with the hinge piece 6 is to adjust the angle of the carriage;

connect through articulated elements 6 between carriage 1 and the horizontal bearing bar 2, then the carriage passes through articulated elements 6 and adjusts suitable angle under the effect of gravity, be fit for the workman and work in the carriage, but the workman need not rock at the during operation carriage, otherwise danger can take place, add a steady board of dimension this moment, couple together carriage 1 and pulley 5, the shelf truck during operation, pulley 5 is fixed, the bearing effect has been played, keep stable under the effect of gravity and rectilinear movement structure 4, it is fixed that steady board 7 also can be because the pulley is stable, thereby carriage 1 obtains stably.

The width of slider 405 is greater than the width of through-hole 402 to slider 405 can drive pulley 5 and slide on horizontal bearing bar 2, and can not make slider 405 break away from with the contact of horizontal bearing bar 2, ensures the security.

The spacing support 3 and the rectilinear movement subassembly 4 of 2 both sides of every horizontal bearing bar all are the symmetric distribution, and the spacing support 3 and the rectilinear movement subassembly 4 of 2 both sides of every horizontal bearing bar all distribute on same water flat line, and four edges of carriage 1 all connect through maintaining steady board 7 on the connecting rod, maintain steady board 7 and comprise a plurality of articulated plate bodies or the body of rod in proper order.

It should supplement and explain that, the limit bracket 3 and the linear motion assembly 4 on the two sides of the horizontal bearing rod 2 are symmetrically distributed so as to achieve the purpose that the stress on the two sides of the whole rack vehicle is even, and the limit bracket 3 and the linear motion assembly 4 are required to be on the same horizontal line, so that the overall stability can be ensured to the maximum extent.

The above embodiments are only exemplary embodiments of the present application, and are not intended to limit the present application, and the protection scope of the present application is defined by the claims. Various modifications and equivalents may be made by those skilled in the art within the spirit and scope of the present application and such modifications and equivalents should also be considered to be within the scope of the present application.
