Translating device, it includes support, translation oil cylinder, support cylinder and supporting leg, and support passes through slide construction and support base
Below connect, translation oil cylinder energy driving arm it is relative with support base slide, enable trestle opposite brackets swing needed for angle, branch
The upper end of support oil cylinder is fixedly connected with support, and lower end is fixedly connected with supporting leg, to adjust the distance between trestle and ground.
Preferably, described driven pulley is steel wheel, and its a diameter of 15~30cm, width is 50~80cm.
Preferably, described slide construction sets guide rail for the bottom of support base, and guide rail is led with what is set on support
Track slot is nested, and trestle is carried out horizontal hunting along the guide groove on support in the presence of translation oil cylinder.
Preferably, the translation oil cylinder is arranged on support.
Preferably, the guide rail is arc-shaped guide rail using the summit of the trestle of swing as the center of circle, the guide groove be with
Arc-shaped guide rail groove corresponding to arc-shaped guide rail.
The advantages of the utility model：Compared with the supporting construction of traditional movable trestle rear end, supporting construction of the invention
Simply, driven pulley is circular steel cylinder, and fault rate is low, without operation, after track drive walking, can directly drag the direct row of driven pulley
Walk；The driven pulley of supporting construction of the present utility model can be not only used for walking, it can also be used to and after walking terminates, vehicle can be by,
More than 100 tons of weight can be born；It is easy to operate without installing support cylinder over the ground again, avoid over the ground support cylinder because will
Bear the weight of trestle itself half and occur cylinder piston rod deformation, cylinder seal oil leak, the peace of oil cylinder in the process of walking
Seat and connecting screw deformation etc. are filled, overcomes and occurs what trestle center line deviateed with tunnel center line because cylinder piston rod deforms
Phenomenon, the safety progress of construction is ensured；Trestle is realized horizontal movement by translating device, realize quick adjustment trestle
Center line overlaps with the center line of inverted arch, ensures the normal construction of inverted arch.
Brief description of the drawings
The utility model is described in further detail below in conjunction with the accompanying drawings：
Fig. 1 is a kind of side view of the rear support structure of self-propelled hydraulic crawler belt trestle of the utility model.
1 support base；2 supports；3 support cylinders；4 supporting legs；5 support bars；6 driven pulleys；7 trestles；8 guide rails；9 guide grooves；10
Translation oil cylinder.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings, to make those skilled in the art with reference to explanation
Book word can be implemented according to this.
As shown in figure 1, a kind of rear support structure of self-propelled hydraulic crawler belt trestle, it includes：
Support base 1, it is fixed on the bottom surface of trestle spandrel girder, and there is support base 1 end of two spandrel girders, for supporting
Trestle 7；
Support bar 5, it is arranged on the bottom surface of support base 1, perpendicular to the ground；
Driven pulley 6, the both ends of central shaft are connected by two support bars 5 with support base 1, and two are set in the rear end of trestle
Individual driven pulley 6, play support trestle 7 and walking；
Translating device, it includes support 2, translation oil cylinder 10, support cylinder 3 and supporting leg 4, support 2 by slide construction with
Connected below support base 1, the energy driving arm 2 of translation oil cylinder 10 is relative with support base 1 to be slided, and the opposite brackets 2 of trestle 7 is put
Angle needed for dynamic, the upper end of support cylinder 3 are fixedly connected with support 2, and lower end is fixedly connected with supporting leg 4, to adjust trestle 7 and ground
The distance between face.
Rear support structural support of the present utility model is simple in construction, and fault rate is low, without operating, after track drive walking,
Driven pulley can directly be dragged directly to walk；Driven pulley can be not only used for walking, it can also be used to the support walked after terminating, can bear
More than 100 tons of weight, meets the needs of live；Driven pulley does not move power, and the width of trestle is longer in moving process,
If Uneven road or tunnel bending etc. make the center line of trestle rear end deviate the center line of tunnel inverted arch, the center of trestle is adjusted
Line overlaps very difficulty with inverted arch center line, by translating device faster easy adjustment trestle center line can be realized with facing upward
Encircle the coincidence of center line, ensure the normal construction of inverted arch.
Further preferred embodiment, described driven pulley 6 are steel wheel, its a diameter of 20cm, width 70cm.After prop up
The driven pulley of support structure is walked using steel wheel conduct and BOGEY WHEEL, and in service life more long, quality is more stable, bears weight more
Greatly, walking is more convenient, and need not be operated, therefore can reduce work rate, improves the efficiency of trestle walking.It is certain by setting
The driven pulley of diameter and width, while making trestle movement easy, and can bears heavier weight.
Further preferred embodiment, described slide construction for support base 1 bottom set guide rail 8, and guide rail 8 with
The guide groove 9 set on support 2 is nested, and makes trestle 7 can be along the guide groove 9 on support 2 in the presence of translation oil cylinder 10
Carry out horizontal hunting.
By setting the guide rail of arc and the guide groove for the arc being nested with guide rail, trestle is set to be swung, with
The center line for being conveniently adjusted the center line and inverted arch tunnel of trestle coincides, and can mitigate again when trestle integrally moves repeatedly and adjust
Destruction of the driven pulley to inverted arch top layer cement layer during center line.
Further preferred embodiment, the translation oil cylinder 10 are arranged on support 2.
Further preferred embodiment, the guide rail 8 are the arc-shaped guide rail using the summit of the trestle 7 of swing as the center of circle,
The guide groove 9 is arc-shaped guide rail groove corresponding with arc-shaped guide rail.
Embodiment of the present utility model so works：After hydraulic track drives trestle to be moved to specified location, detection
Whether trestle center line overlaps with inverted arch center line, if the center line of the center line of trestle rear end and inverted arch is not on the same line
When, support cylinder is extended, support trestle makes driven pulley leave ground, and by translation oil cylinder, adjustment trestle is swung, and makes trestle
Support cylinder is packed up on same straight line, driven pulley is supported on inverted arch by the center line of center line and inverted arch.
Although embodiment of the present utility model is disclosed as above, it is not restricted in specification and embodiment
Listed utilization, it can be applied to various suitable fields of the present utility model completely, for those skilled in the art,
Other modification is easily achieved, therefore under the universal limited without departing substantially from claim and equivalency range, this reality
Specific details is not limited to new and shown here as the embodiment with description.
