And the service life of the base is prolonged, and the use cost of equipment is reduced.

Description

Technical Field

[0001] The utility model belongs to the technical field of rail stretching machine bases, and particularly relates to a novel rail stretching machine base. Background Art

[0002] The rail stretching machine is suitable for railway rail operations, which includes a hydraulic system, a stretching base, etc.

[0003] Patent CN214379103U discloses a fixed card holder, including a card holder body, a connecting ear, a card slot and a limiting protrusion. Two connecting ears parallel to each other are arranged on both sides of the card holder body, a card slot is arranged at the bottom of the card holder body, an insertion port and a supporting port are arranged at both ends of the card slot, a limiting slot is arranged at the top of the card slot, and limiting protrusions are symmetrically arranged on both sides of the bottom of the card slot. The utility model prevents the inserted device from falling off by respectively arranging supporting ports and insertion ports of unequal widths at both ends of the card holder body, and at the same time, a limiting protrusion parallel to the inner wall of the card slot is arranged inside the card slot, which cooperates with the corresponding groove body arranged on the side wall of the device to achieve clamping and fixing. At the same time, since the limiting protrusion is arranged obliquely, it can prevent the device from being separated from the card holder from the supporting port, thereby achieving the fixation of the device and ensuring the stability of the clamping. Moreover, no external fixing structure is required, which is convenient for disassembling the device on the card holder, and has strong practicality.

[0004] The fixed card seat in the above patent is the stretching base, which is generally made of "7075-T6 aviation aluminum alloy". It has the advantages of light weight, good toughness, and easy to carry; but the card rail groove is greatly worn under the action of large external forces, and the base is easy to deform as a whole; the service life of the base is short and the maintenance cost is high. Utility Model Content

[0005] The utility model provides a novel rail stretching machine base, which can solve the problems pointed out in the background technology.

[0006] A novel rail stretching machine base comprises a base body, wherein the base body comprises a base body and a rail clamping groove, and the rail clamping groove is lined with a wear-resistant sleeve.

[0007] Preferably, the wear-resistant sleeve is a steel sleeve.

[0008] Preferably, both ends of the steel sleeve are connected to steel plates, and the steel plates at both ends are connected to two end surfaces of the seat body.

[0009] Beneficial effects: The utility model provides a new type of rail stretching machine base. Without changing the existing functions, a steel sleeve is installed in the rail groove to increase the strength of the rail groove and greatly reduce the wear of the rail groove; steel plates are installed on the two end faces of the base to connect with the steel sleeve as a whole and are fixedly connected to the base, which increases the overall rigidity of the base and reduces the deformation under the action of a large external force; that is, the strength of the rail groove of the base is improved and the wear of the rail groove is reduced; the base has good integrity and is not easy to deform. The service life cycle of the base is increased and the use cost of the equipment is reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 It is a structural schematic diagram of the utility model.

[0011] Description of reference numerals:

[0012] Reference numerals in the figure: seat body 1; rail groove 2; wear-resistant sleeve 3; steel plate 4. DETAILED DESCRIPTION

[0013] A specific implementation of the present utility model is described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present utility model is not limited by the specific implementation mode.

[0014] Example 1: Figure 1 As shown, a new type of rail stretching machine base includes a base body, the base body includes a base body 1 and a rail groove 2, the rail groove 2 is lined with a wear-resistant sleeve 3, and the wear-resistant sleeve 3 is a steel sleeve.

[0015] Preferably, both ends of the steel sleeve are welded to the steel plates 4, and the steel plates 4 at both ends are connected to the two end surfaces of the seat body 1 by bolts.

[0016] The above disclosures are only several specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
