Description

Technical Field

[0001] The utility model relates to an on-track pushing machine, in particular to an on-track pushing machine provided with a compensation mechanism. Background Art

[0002] The on-rail heavy object pusher consists of two components: a clamping unit and a push cylinder. Used in conjunction with two hydraulic pump stations, it can move heavy objects such as shields, assembly machines, and trolleys to designated locations using rails. This new and effective tool replaces traditional methods like sleepers and rollers for moving heavy objects.

[0003] However, due to the limited length of the piston rod in the push cylinder, the distance the device can be moved is limited. It is necessary to repeatedly change the position of the clamp to achieve long-distance movement of the device. To change the position of the clamp, the piston rod in the push cylinder is extended to the required distance, and then the clamp is released. Then, the piston rod in the push cylinder is reset to drive the push cylinder and the clamp forward. However, the efficiency of the piston rod in the existing push cylinder is low when resetting, resulting in low efficiency of the entire pushing operation. If its efficiency needs to be accelerated, an oil supply power device needs to be installed on the cylinder to pump oil into one end of the piston rod through the oil supply power device to accelerate the reset of the piston rod. However, this method is expensive because it requires the installation of additional power equipment. For this reason, an on-track pushing machine with a compensation mechanism is proposed. Utility Model Content

[0004] The purpose of the utility model is to solve the above problems and to provide an on-track pusher provided with a compensation mechanism.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solution: an on-track pushing machine provided with a compensation mechanism, comprising a clamp and a pusher mounted on the clamp; its characteristic is that it also includes a compensator mounted on the pusher to compensate for the reset of the pusher and accelerate the reset of the pusher; the pusher includes an oil cylinder connected to the clamp and a piston movably mounted in the oil cylinder; the compensator includes a compensation shell mounted on the oil cylinder and connected to the oil chamber in the oil cylinder, a compensation piston movably mounted in the compensation shell and a compensation spring mounted between the compensation piston and the bottom of the compensation shell.

[0006] Further preferably, a positioning recess is provided on the oil cylinder, and a positioning block corresponding to the positioning recess is provided on the compensation shell.

[0007] More preferably, it further includes a fixing block arranged at corresponding positions on the oil cylinder and the positioning block.

[0008] Further preferably, the oil cylinder is provided with an oil inlet and an oil outlet, and the oil outlet is communicated with the compensation shell.

[0009] Further preferably, the clamp includes a clamping cylinder, a clamping piston rod movably installed in the clamping cylinder, and a clamping portion provided on the clamping cylinder and cooperating with the clamping piston rod for clamping; the clamping cylinder is also provided with a connecting portion for installing a connecting cylinder.

[0010] The beneficial effects of the utility model are as follows: through the arrangement of the compensator, after the track device is pushed on the track by the pusher, the clamp releases the clamped track, and the compensator compensates for the reset speed of the piston, thereby accelerating the reset speed of the piston, and accelerating the clamp to move forward into position and then clamp again for pushing again, thereby improving the working efficiency of the on-track pusher;

[0011] By arranging a positioning recess on the oil cylinder and a positioning block on the compensation shell, the position where the compensator is installed on the oil cylinder is limited, which facilitates installation and improves assembly efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Next, we will further explain the on-track pusher with a compensation mechanism described in the present invention with reference to the accompanying drawings.

[0020] It should be noted that all directional indications such as up, down, left, right, front, back, etc. in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components in a certain specific posture as shown in the accompanying drawings. If the specific posture changes, the directional indication will also change accordingly.

[0021] In this utility model, unless otherwise specified or limited, the terms "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can mean fixed connection, detachable connection, or integration; it can mean mechanical connection or electrical connection; it can mean direct connection or indirect connection through an intermediate medium; it can mean internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0022] See Figures 1-6 As shown in, an on-track pusher with a compensation mechanism comprises a clamper 1 and a pusher 2 mounted on the clamper 1; it is characterized in that it also comprises a compensator 3 mounted on the pusher 2 to compensate for the reset of the pusher 2 and accelerate the reset of the pusher 2; the pusher 2 comprises an oil cylinder 21 connected to the clamper 1 and a piston 22 movably mounted in the oil cylinder 21; the compensator 3 comprises a compensation shell 31 mounted on the oil cylinder 21 and connected to the oil chamber in the oil cylinder 21, a compensation piston 32 movably mounted in the compensation shell 31 and a compensation spring 33 mounted between the compensation piston 32 and the bottom of the compensation shell 31; the oil cylinder 21 is provided with an oil inlet 5 and an oil outlet 51, and the oil outlet 51 is connected to the compensation shell 31;

[0023] By setting the compensator 3, after the track device is pushed on the track by the pusher, the clamper 1 releases the clamping track, and the compensator 3 compensates for the reset speed of the piston 22, speeding up the reset speed of the piston 22, and accelerating the clamper 1 to move forward into position and then re-clamp and push again, thereby improving the working efficiency of the on-track pusher;

[0024] At the same time, a spring and a compensation piston 32 are arranged in the compensator 3. When the oil cylinder 21 pushes the piston 22 to move and pushes the track equipment to move, the piston 22 squeezes the oil and presses the oil into the compensation shell 31 through the oil outlet 51. The oil entering the compensation shell 31 squeezes the compensation piston 32, and the compensation piston 32 squeezes the compensation spring 33 to cause it to contract. When the piston 22 is reset, the reset force of the compensation spring 33 pushes the compensation piston 32 to move, and the compensation piston 32 presses the oil back into the oil cylinder 21 through the oil outlet 51 to push the piston 22 to reset, thereby accelerating the reset speed of the piston 22, and no external power is required to push the piston 22 to reset.

[0025] In one embodiment, the oil cylinder 21 is provided with a positioning recess 4, and the compensation shell 31 is provided with a positioning block 41 corresponding to the positioning recess 4;

[0026] By providing a positioning recess 4 on the oil cylinder 21 and a positioning block 41 on the compensation shell 31, the position of the compensator 3 installed on the oil cylinder 21 is limited, which facilitates installation and improves assembly efficiency.

[0027] After being positioned by the cooperation between the positioning recess 4 and the positioning block 41 , the compensation shell 31 can be fixedly connected by welding to avoid deviation of the welding position.

[0028] In one embodiment, it further includes a fixing block 42 that is disposed on the oil cylinder 21 and the positioning block 41 at corresponding positions, and the compensation shell 31 can also be fixedly connected by locking the fixing block 42 with bolts.

[0029] In one embodiment, the clamp 1 includes a clamping cylinder 11, a clamping piston rod 12 movably installed in the clamping cylinder 11, and a clamping portion 13 arranged on the clamping cylinder 11 and cooperating with the clamping piston rod 12 for clamping; the clamping cylinder 11 is also provided with a connecting portion 14 for installing a connecting cylinder 21.

[0030] After the oil cylinder 21 moves into place, the clamping cylinder 11 is controlled to clamp the rail again, and then the oil cylinder 21 can be supplied with oil again by the oil supply device to push the piston 22 forward. During the forward movement of the piston 22, the rail device is pushed to move along the rail, and the oil in the oil cylinder 21 on one side of the piston 22 is squeezed into the compensation shell 31; when the piston 22 is extended to the full stroke, the clamping cylinder 11 is controlled to release the rail and the oil supply is stopped at the same time. At this time, the compensation piston 32 is pushed forward by the reset force of the compensation spring 33, and the compensation piston 32 presses the oil into the oil cylinder 21. At this time, since the piston 22 is connected to the rail device, the oil is pressed into the oil cylinder 21, and the oil cylinder 21 drives the clamp 1 to move forward along the rail. After the oil cylinder 21 moves into place, the clamping cylinder 11 is controlled again to clamp the rail, and then the oil supply device can be used to supply oil to the oil cylinder 21 again to push the rail device to move again. The cycle action continuously pushes the rail device to move along the rail.

[0031] The protection scope of the present invention is not limited to the above embodiment and its variations. Conventional modifications and replacements made by those skilled in the art based on the contents of this embodiment fall within the protection scope of the present invention.
