Description

Technical Field

[0001] The utility model belongs to the technical field of tunnel construction horizontal transportation devices or equipment, and particularly relates to a tunnel battery car track-lifting tooling. Background Art

[0002] In the construction of shallow-buried and mined tunnels of urban subways, in order to ensure construction safety, the shield method is mostly used for construction. In shield method construction, the horizontal transportation in the tunnel generally adopts the form of a battery locomotive head towing a slag bucket car, a segment car, and a mortar car to transport segments, synchronous grout, and muck for external transportation and other materials in shield construction. During the driving process of the battery locomotive group on the pre-laid temporary track, due to uncertain factors such as track linear deviation and wheel flange wear of the locomotive wheels, it is inevitable that the wheels of the battery car will derail. After the battery tractor derails, a jack is often directly used to lift the equipment, and then the jack is used for inclined jacking to adjust the battery tractor onto the track. Due to tunnel construction, the space is relatively narrow, and for inclined jacking with a jack, the working surface of the jack is relatively small, there is a risk of the jack slipping or the jack being damaged due to inclined jacking, resulting in equipment overturning and injury. Moreover, the track-lifting time is long, the success rate of one-time track-lifting is unstable, and it is often necessary to adjust the jack multiple times to adjust the equipment in place, which is time-consuming and laborious, highly dependent on construction experience, and the construction process has not formed a procedure, affecting the normal continuous advancement of shield construction. Summary of the Invention

[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the above-mentioned prior art and provide a tunnel battery car track-lifting tooling with a short cycle, fast speed, safety and reliability, high success rate, and easy to form a process.

[0004] The technical solution adopted to solve the above technical problem is: a tunnel battery car track-lifting tooling, including a tooling body. The cross-sectional shape of the tooling body is rectangular. A sliding wheel set is arranged in the middle of the upper part of the tooling body. The sliding wheel set is fixedly connected with a cage. The sliding wheel set and the tooling body can move relative to each other. The connection part of the battery car is placed on the cage and the sliding wheel set. Two groups of vertical jacks are arranged on both sides of the tooling body for jacking. One end of the vertical jack is placed on the ground and the other end jacks from the lower part of the tooling body. One end of the horizontal jack contacts the body of the battery car and the other end is arranged on the longitudinal section of the tooling body.

[0005] A U-shaped groove is arranged in the middle of the tooling body of the utility model. The sliding wheel set and the cage are arranged at the bottom of the U-shaped groove and can slide back and forth along the bottom of the U-shaped groove.

[0006] Two groups of stiffening ribs are arranged between the bottom and the side wall of the U-shaped groove of the utility model.

[0007] One end of the horizontal jack of the utility model contacts the body of the battery car and the other end is arranged on the side wall of the U-shaped groove.

[0008] On both sides of the lower part of the tooling body of the present utility model, grooves are provided, and the ends of the vertical jacks are abutted against the horizontal planes of the grooves.

[0009] The length of the bottom of the U-shaped groove of the present utility model is greater than the width of the track.

[0010] The transverse jack of the present utility model is a split hydraulic jack.

[0011] Since the present utility model adopts the arrangement of the cage and the sliding wheel set on the tooling body, the connection part of the derailed battery car is placed on the cage and the sliding wheel set. By using two groups of vertically arranged jacks to lift the tooling body and the battery car to generate a distance of 2-3 cm from the rail surface, and then using the horizontally arranged split hydraulic jack to lift, the battery car, the cage and the sliding wheel set are integrally translated in the width direction of the track, so that the wheels are located on the rail surface, and the track lifting work is completed. This device is convenient for construction personnel to operate in a narrow construction space, effectively reduces the equipment damage rate and the construction risk of personnel, avoids the number of repeated adjustments, and can complete the track lifting work at one time.

[0015] The following further describes the present utility model in detail with reference to the drawings and embodiments, but the present utility model is not limited to these embodiments.

[0016] Embodiment 1

[0017] In Figure 1 , 2Among them, a tunneling battery car track-lifting tooling involved in the present utility model includes a tooling body 1. The cross-sectional shape of the tooling body 1 is rectangular. In this embodiment, a U-shaped groove 1-2 is machined in the middle of the tooling body 1. A sliding wheel set 4 and a cage 3 are arranged at the bottom of the U-shaped groove 1-2. The sliding wheel set 4 and the cage 3 are fixedly connected and can slide back and forth along the bottom of the U-shaped groove 1-2 as a whole. The cage 3 prevents the sliding wheel set 4 from having a lateral displacement on the tooling body 1 and keeps it in a longitudinal displacement. In order to increase the stability of the whole device, two groups of stiffening ribs 2 are arranged between the bottom and the side wall of the U-shaped groove 1-2. In order to facilitate jacking and at the same time reduce the weight and volume of the tooling, grooves 1-1 are arranged on both sides of the lower part of the tooling body 1. The end of the vertical jack abuts against the horizontal plane of the groove 1-1. During actual use, the connection part of the battery car is placed on the cage 3 and the sliding wheel set 4. Two groups of vertical jacks are arranged on both sides of the tooling body 1. One end of the vertical jack is placed on the ground and the other end jacks up from the groove 1-1 of the tooling body 1. One end of the horizontal jack contacts the body of the battery car and the other end is arranged on the side wall of the U-shaped groove 1-2. In order to facilitate installation and operation, the horizontal jack is a split hydraulic jack. Further, the length of the bottom of the U-shaped groove 1-2 is greater than the width of the track to ensure that both ends of the wheels of the battery car can move smoothly onto the track.

[0018] The using steps of the present utility model are as follows:

[0019] 1. Vertical jacking: Place the tooling body 1 at the tail end of the connection part of the derailed battery car. Use 50t hydraulic jacks at both ends of the tooling body 1 to vertically jack up so that the wheel rims of the battery car are 2-3 cm higher than the rail surface.

[0020] 2. Horizontal jacking and translation: After using 50t hydraulic jacks at both ends of the tooling body 1 to vertically jack up so that the wheel rims of the battery car are 2-3 cm higher than the rail surface, place the split hydraulic jack horizontally on the longitudinal section of the tooling body 1 (i.e., on the side wall of the U-shaped groove 1-2). Under the jacking action of the split hydraulic jack, the battery car, the cage 3 and the sliding wheel set 4 are translated horizontally to the predetermined track position so that both ends of the wheels are located on the rail surface, and the split hydraulic jack is depressurized and withdrawn from the work station.

[0021] 3. Depressurize the vertical jacking hydraulic jack and withdraw it from the work station, and withdraw the tooling body 1 from the work station to complete this track-lifting work.
