DETAILED DESCRIPTION
[0025] The present application is further described in detail below in conjunction with all the drawings and specific embodiments.
[0026] Reference Figure 1 The present invention provides a rail adjustment device, which is arranged between the gaps between two sleepers and is used to fine-tune the inclination angle of the rail. The device comprises a base 1, a feed pipe 2, a limit assembly 3, a fixing frame 4 and a holding frame 5. The limit assembly 3, the fixing frame 4 and the holding frame 5 are all arranged above the base 1. The rail can first pass through the feed pipe 2 and the limit assembly 3 to perform the first step of limiting the rail, and then pass through between the fixing frame 4 and the holding frame 5. The holding frame 5 moves relative to the fixing frame 4, thereby adjusting the pressure on the rail and adjusting the inclination angle of the rail.
[0027] Reference Figure 1 and Figure 2 The limiting assembly 3 includes a first support platform 31 and two limiting wheels 32. The support platform is fixed to the upper side of the base 1, and the limiting wheels 32 are rotatably connected to the upper side of the support platform. The axis direction of the limiting wheels 32 is vertically arranged so that the limiting wheels 32 can rotate on the upper side of the base 1. The two limiting wheels 32 are close to each other and can abut against the waist of the rail, thereby limiting the horizontal direction of the rail after entering the adjustment device. It should be noted that the support platform is only used to increase the height of the limiting wheels 32 so that the limiting wheels 32 can match the positions of the corresponding feed pipe 2, the fixing frame 4 and the holding frame 5. The limiting wheels 32 can also be directly rotated on the base 1, as long as the limiting wheels 32 can rotate.
[0028] The fixing frame 4 includes a bottom plate 41 and two fixed side plates 42. The bottom plate 41 is fixed to the upper side of the base 1 of the base 1. A gap is provided between the two fixed side plates 42. The two fixed side plates 42 are fixed to the upper side of the bottom plate 41. A support wheel 43 is rotatably connected between the two fixed side plates 42. The axial direction of the support wheel 43 is horizontally arranged, and the axial direction of the support wheel 43 is perpendicular to the penetration direction of the rail, so that the support wheel 43 can be rotatably connected to the fixing frame 4, and the support wheel 43 can abut against the lower side of the rail.
[0029] The holding frame 5 is located above the fixed frame 4. The holding frame 5 and the end of the fixed frame 4 close to the limit assembly 3 can rotate relative to each other, so as to limit the rail and press and change the inclination angle of the rail. Specifically, the holding frame 5 includes a top plate 51 and two holding side plates 52. The two holding side plates 52 are fixed to the lower side of the top plate 51. A lower pressing wheel 53 is rotatably connected between the two holding side plates 52. The lower pressing wheel 53 can abut against the upper side of the rail. The upper end of the fixed side plate 42 and the lower end of the holding side plate 52 are rotatably connected through a horizontally arranged rotating shaft 6. The setting position of the rotating shaft 6 is such that the holding frame 5 and the fixed frame 4 are close to the limit assembly 3, so that the holding frame 5 can press and deform the rail. When in use, first pass the rail between the two limiting wheels 32, the limiting wheels 32 limit the rail waist in the horizontal direction, and then move the rail so that the rail moves between the lower pressure wheel 53 and the supporting wheel 43. The supporting wheel 43 and the lower pressure wheel 53 can limit the rail in the vertical direction, so as to determine the position of the rail. At this time, one end of the pressing frame 5 rotates downward, and the lower pressure wheel 53 presses the rail downward so that the rail can be deformed to tilt downward, thereby completing the fine adjustment of the inclination angle of the rail to meet construction requirements. The limiting wheel 32, the lower pressure wheel 53 and the supporting wheel 43 position the rail, thereby improving the work efficiency when adjusting the rail.
[0030] As an embodiment, a pressure rod 54 is fixed on the upper side of the pressure holding frame 5. Specifically, the pressure rod 54 is fixed on the top plate 51 at an angle, and the end of the pressure rod 54 away from the pressure holding frame 5 is tilted toward the side away from the limit assembly 3. During operation, the worker can manually press the pressure rod 54 to adjust the inclination angle of the rail.
[0031] As an embodiment, multiple pneumatic springs are arranged between the bottom plate 41 and the top plate 51. Specifically, two gas springs 7 are provided. The gas spring 7 is located at one end of the fixing frame 4 and the pressing frame 5 away from the limit assembly 3. The two ends of the gas spring 7 are rotatably connected to the bottom plate 41 and the top plate 51 respectively. After pressing the pressing frame 5, the gas spring 7 can support the pressing frame 5 to return to its original position so that subsequent work can continue.
[0032] As an embodiment, a limiting groove 431 is provided in the middle of the support wheel 43. The limiting groove 431 is provided on the circumference of the support wheel 43. The rail can be placed in the limiting groove 431, thereby further improving the limiting effect of the rail.
[0033] A second support platform 21 is fixed to the lower side of the feed pipe 2, which is fixed to the upper side of the base 1. The rail can be inserted into the feed pipe 2 so that the rail can then accurately enter the limit assembly 3. Furthermore, a bell tube 22 is fixed to one end of the feed pipe 2. The open end of the bell tube 2 is arranged away from the feed pipe 2, thereby increasing the area of the feed port of the feed pipe 2 and facilitating the accurate delivery of the rail into the adjustment device.
[0034] The implementation principle of the present utility model is as follows: when in use, the rail is first passed between the two limiting wheels 32, the limiting wheels 32 limit the rail waist in the horizontal direction, and then the rail is moved so that the rail moves between the lower pressure wheel 53 and the supporting wheel 43. The supporting wheel 43 and the lower pressure wheel 53 can limit the rail in the vertical direction, so as to determine the position of the rail. At this time, one end of the pressing frame 5 rotates downward, and the lower pressure wheel 53 presses the rail downward so that the rail can be deformed to tilt downward, thereby completing the fine adjustment of the inclination angle of the rail to meet construction requirements. The limiting wheel 32, the lower pressure wheel 53 and the supporting wheel 43 position the rail, thereby improving the work efficiency when adjusting the rail.
[0035] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
