Description

Box culvert loop wheel machine grasping system

Technical Field

The invention belongs to the field of underground shield construction equipment, and particularly relates to a box culvert crane grabbing system.

Background

At present, in the construction process of a domestic high-speed railway or subway construction tunnel, box culvert transportation is one of important construction processes, and the quick and efficient realization of box culvert transportation is an important guarantee of construction progress. At present, the domestic tunnel construction mainly adopts fixed track transportation and needs to lay a track. The track can cause other construction vehicles to pass through the road and occupy or can not pass through, and fixed rail vehicle operation is inflexible moreover, still needs other vehicles to carry out the supplementary case culvert of switching to it outside the tunnel. Therefore, the construction cost of the fixed rail vehicle is high, the equipment investment is large, and the construction period is long. Aiming at the problem, engineering technicians provide that wheeled vehicles are used for transportation, the wheeled vehicles are high in speed and flexible in steering, other auxiliary vehicles are not needed for transporting box culverts, and the tunnel can run in parallel with other construction vehicles or make a mistake in driving. But wheeled vehicle transports box culvert time in order to can raise the efficiency, often need whole car to draw two piece box culverts at least and just can guarantee high efficiency. The box culvert is generally wider, and if the box culvert is transversely placed during transportation of the wheeled vehicle, the whole machine is over wide due to the placement of the box culvert, and other vehicles cannot run when entering a tunnel for transportation, so that the efficiency of transporting the box culvert by the wheeled vehicle is also restricted. The box culvert on the existing market transports and can adopt loop wheel machine grasping system to transport, and what most box culvert loop wheel machine grasping system adopted is the vacuum chuck formula, and it is flexible through the pneumatic cylinder to snatch the position through the flexible control of pneumatic cylinder, carries out 90 rotations to the box culvert.

In order to achieve the purpose, the technical scheme of the invention is realized as follows:

the utility model provides a box culvert loop wheel machine grasping system, includes walking support, running gear, track, drive arrangement, electric block and lifts by crane the bracket, running gear is equipped with two sets ofly, running gear and track sliding connection are equipped with the walking support between the running gear, the lower extreme of walking support install drive arrangement, the drive arrangement lower extreme install four electric block respectively, the four corners of lifting by crane the bracket respectively with every electric block's bottom fixed connection.

Furthermore, a slewing bearing is arranged on the driving device, and the slewing bearing is in transmission connection with the driving device.

Furthermore, the hoisting bracket is a C-shaped structure frame.

Furthermore, a stop block is arranged at the contact part of the lower part of the hoisting bracket and the box culvert.

Furthermore, the stop block is a high-density polyethylene stop block.

Compared with the prior art, the box culvert crane grabbing system has the following advantages:

the utility model discloses a behind such structure for the installation of box culvert is simple, no longer receives the installation rate of box culvert in the installation, very big shortening the whole time limit for a project, improved efficiency. The utility model discloses a structure is promptly itself also become simple, and the fault rate is lower, and the good reliability of box culvert transportation.

Detailed Description

It should be noted that the embodiments and features of the embodiments of the present invention may be combined with each other without conflict.

In the description of the present invention, it is to be understood that the terms "central," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like are used in the orientation or positional relationship indicated in the drawings, which are merely for convenience in describing the invention and to simplify the description, and are not intended to indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and are therefore not to be construed as limiting the invention. Furthermore, the terms "first", "second", etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first," "second," etc. may explicitly or implicitly include one or more of that feature.

The specific meaning of the above terms in the creation of the present invention can be understood by those of ordinary skill in the art through specific situations.

The invention will be described in detail with reference to the following embodiments with reference to the attached drawings.

The utility model provides a box culvert loop wheel machine grasping system, includes walking support 6, running gear 8, track 11, drive arrangement 7, electric block 9 and lifts by crane bracket 10, running gear 8 is equipped with two sets ofly, and running gear 8 and track 11 sliding connection are equipped with walking support 6 between running gear 8, the lower extreme of walking support 6

install drive arrangement

7, 7 lower extremes of drive arrangement install four electric block 9 respectively, the four corners of lifting by crane bracket 10 respectively with every electric block 9's bottom fixed connection.

A slewing bearing is arranged on the driving device 7, and the slewing bearing is in transmission connection with the driving device 7; the hoisting bracket 10 is a C-shaped structural frame; a stop block is arranged at the contact part of the lower part of the hoisting bracket 10 and the box culvert; the stop block is a high-density polyethylene stop block.

The effect of box culvert loop wheel machine snatch the box culvert, then walk to assigned position through running gear 8 on loop wheel machine roof beam track 11, put in place the box culvert installation.

The box culvert crane lifts the box culvert from the plate trailer of the automobile, rises to a high position, and then travels forwards through the crane beam rail 11. And stopping intermittently in the walking process to complete the reversing of the box culvert, and finally unloading the box culvert to a position where the box culvert needs to be installed to complete one working cycle.

As shown in fig. 1, 2 and 3, the modified grabbing system mainly comprises a rotary hydraulic cylinder 1, an up-down telescopic hydraulic cylinder 2, a guide pillar 3, a grabbing disc 4 and a clamping hydraulic cylinder 5. The grabbing system is too compact in structure and high in failure rate, and once the clamping hydraulic cylinder 5 fails, the vacuum chuck cannot suck the box culvert or the box culvert falls off in the hoisting process.

As shown in fig. 4, 5 and 6, a slewing bearing and driving device 7 is mounted on the lower portion of the traveling bracket 6, four hoisting electric hoists 9 are mounted on the lower portion of the slewing bearing and driving device 7, and four hoisting brackets 10 are hoisted by the electric hoists. When the box culvert crane travels to the side surface of the box culvert to be hoisted, the traveling device 8 drives the traveling support 6 to move towards the box culvert, the hoisting bracket 10 is driven to fork the box culvert, and the high-density polyethylene stop block is arranged at the position, contacted with the box culvert, of the lower part of the hoisting bracket 10, so that the box culvert is prevented from being collided in the forking process.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and should not be taken as limiting the invention, so that any modifications, equivalents, improvements and the like, which are within the spirit and principle of the present invention, should be included in the scope of the present invention.
