A paving aid for elastic pads with limited grooves

Abstract

The present invention discloses an auxiliary device for laying elastic pads in limited grooves, which belongs to the technical field of ballastless track construction. In view of the shortcomings of the existing technology, the present invention provides an auxiliary device for laying elastic pads in limited grooves, comprising an I-shaped base frame and a T-shaped pull rod slidably mounted on the I-shaped base frame, and brush buckets are provided at both ends of the T-shaped pull rod. The brush buckets at both ends of the T-shaped pull rod of the present invention can support the elastic pad, and at the same time, the I-shaped base frame can allow the elastic pad in contact to be completely tightly attached to the inner side of the limited groove. The brush buckets at both ends of the T-shaped pull rod support the elastic pad to prevent the elastic pad from hollowing and warping during the laying process.

Description

Technical Field

[0001] The invention relates to a limiting groove elastic pad paving auxiliary device, belonging to the technical field of ballastless track construction. Background Art

[0002] A limiting groove needs to be reserved on the base plate of the ballastless track for the subsequent pouring of self-compacting concrete to achieve the connection between the base plate and the upper pad. During construction, the inner wall of the limiting groove needs to be bonded with an elastic pad.

[0003] In the prior art, it is necessary to manually tap with a rubber hammer to form a bond between the elastic pad and the limiting groove. This method cannot ensure that the concrete and the elastic pad are tightly attached, or some parts are not tightly attached after tapping. This can easily cause the self-compacting concrete to enter during the pouring process, causing the self-compacting concrete to directly contact the concrete in the limiting groove.

[0004] Therefore, in order to solve the problem that the elastic pad is not tightly attached to the limiting groove during the paving process, it is necessary to design a new auxiliary tool for paving the elastic pad. Summary of the Invention

[0005] In view of the deficiencies in the prior art, the present invention provides a positioning groove elastic pad paving assistant.

[0006] The technical solution provided by the present invention to solve the above technical problems is: a limiting groove elastic pad paving assistant, including an I-shaped base frame and a T-shaped pull rod slidably installed on the I-shaped base frame, and brush barrels are provided at both ends of the T-shaped pull rod.

[0007] A further technical solution is that the I-shaped chassis includes a connecting rod and vertical plates fixed at both ends of the connecting rod, and the connecting rod is provided with a strip-shaped vertical sliding hole vertically in the length direction and a sliding horizontal hole communicating with the sliding hole horizontally.

[0008] A further technical solution is that the T-shaped pull rod includes a vertical rod and a horizontal rod passing through the lower end of the vertical rod; the lower end of the vertical rod is inserted into the sliding vertical hole, and its lower end extends outside the sliding vertical hole; both ends of the horizontal rod pass through the sliding horizontal holes.

[0009] A further technical solution is that a top cap for pulling the pull rod is provided at the upper end of the vertical rod.

[0010] A further technical solution is that a bottom cap is provided at the lower end of the vertical rod to prevent the pull rod from overturning.

[0011] A further technical solution is that the brush barrel includes a connecting cylinder and rotating cylinders arranged at both ends of the connecting cylinder, and the ends of the horizontal rods are fixed on the outer wall of the middle part of the connecting cylinder.

[0012] A further technical solution is that the rotating drum is rotatably mounted on the connecting drum.

[0013] The present invention has the following beneficial effects: the brush barrels at both ends of the T-shaped pull rod of the present invention support the elastic pad, and at the same time, the I-shaped base frame can allow the elastic pad in contact to be completely close to the inner side of the limiting groove. The brush barrels at both ends of the T-shaped pull rod support the elastic pad, preventing the elastic pad from becoming hollow and warping during the laying process.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0023] like Figure 1-7As shown, a limiting groove elastic pad paving assistant of the present invention includes an I-shaped base frame 1 and a T-shaped pull rod 4, the I-shaped base frame 1 includes a connecting rod and vertical plates fixed at both ends of the connecting rod, a strip-shaped sliding vertical hole is vertically provided in the length direction of the connecting rod, and a sliding horizontal hole communicating with the sliding hole is provided horizontally, the T-shaped pull rod 4 includes a vertical rod and a horizontal rod passing through the lower end of the vertical rod; the lower end of the vertical rod is inserted into the sliding vertical hole, and its lower end extends outside the sliding vertical hole; both ends of the horizontal rod pass through the sliding horizontal hole and a brush bucket 3 is installed.

[0024] like Figure 1 As shown, in this embodiment, a top cap 5 for pulling the pull rod is provided at the upper end of the vertical rod, so that effort is saved when pulling the T-shaped pull rod 4.

[0025] like Figure 1 As shown, in this embodiment, a bottom cap 2 is provided at the lower end of the vertical rod to prevent the pull rod from overturning, thereby ensuring the smoothness of the T-shaped pull rod 4 in the sliding hole.

[0026] like Figure 6 As shown, in this embodiment, the brush barrel 3 includes a connecting cylinder and two rotating cylinders. The two rotating cylinders are rotatably mounted on the upper and lower ends of the connecting cylinder respectively, and the end of the horizontal rod is fixed on the outer wall of the middle part of the connecting cylinder.

[0027] During construction of the present invention, the I-shaped chassis 1 is moved to the designated limiting groove, and the I-shaped chassis 1 is placed. The I-shaped chassis 1 directly presses against the elastic pads on the left and right sides, so that the elastic pads on the left and right sides are completely in close contact with the inner sides of the limiting grooves. Hold the top cap 5 by hand, move the T-shaped pull rod 4 left and right to let the upper and lower brush barrels 3 press against the upper and lower elastic pads, so that the upper and lower elastic pads are completely in close contact with the inner sides of the limiting grooves. After the work is completed, move the I-shaped chassis 1 to the next limiting groove.
