Hydraulic pipe coiler and construction machinery

Abstract

The invention discloses a hydraulic pipe coiler and construction machinery. The hydraulic pipe coiler comprises a coiling block, a swivel joint and a bracket. The swivel joint is coaxial with the coiling block, and comprises a jacket and a core. A liquid inlet is reserved in the jacket. The jacket is fixedly arranged on the bracket. One end of the core is nested on the middle part of the jacket in a rotating way, and a liquid outlet is reserved in the other end of the core. The end of the core with the liquid outlet is fixedly connected to one side of the coiling block. The other side of the coiling block is arranged on the bracket in a rotating way. An open hole is reserved in the coiling block. The coiling block and the swivel joint of the hydraulic pipe coiler are connected with each other, and are independent, a joint of the coiling block and the swivel joint is simply structured without influence on a coiling space of the coiling block, and the coiling pipe and the swivel joint of the hydraulic pipe coiler are easy to assemble; the open hole is directly reserved in the coiling block for a pipeline to penetrate through, and an additional convex structure matched with the pipeline is not required, so that an actual coiling space of the coiling block is enlarged, and the space utilization rate of the hydraulic pipe coiler is increased.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a hydraulic hose reel and construction machinery provided with the hydraulic hose reel. Background technique [0002] At present, hydraulic hose reels are mainly used for retracting and unwinding liquid pipeline devices, such as retracting and unwinding water pipes or hydraulic oil pipes. Generally, hydraulic hose reels include reels and rotary joints. The reels are rotatably set on the support frame. One end of the hydraulic hose reel is connected to the pipeline wound on the reel, and rotates with the reel, and the other end is connected to the stationary pipeline, so that the hydraulic hose reel can release or retract the hydraulic pipeline, and at the same time, it can pass through The tubing transports the fluid. [0003] However, the structure of the existing hydraulic hose reels is relatively complicated, such as figure 1 As shown, the structure of the connection between the rotar...

Problems solved by technology

[0003] However, the structure of the existing hydraulic hose reels is relatively complicated, such as figure 1 As shown, the structure of the connection between the rotary joint 1' and the reel 2' is mainly complicated. In order to make the pipeline 4' connect from the outlet of the rotary joint 1', it can transition smoothly and be wound on the reel 2'. A protruding structure 3' will be set on the reel 2' near the left baffle, and the pipeline 4' will be connected to the outlet of the rotary joint 1' at the protruding structure 3'

This protruding structure 3' reduces the actual winding space of the reel 2', and the processing and assembly of the protruding structure 3' is usually more complicated; in addition, the rotary joint 1' and the reel 2' are not independent of each other, and the assembly of the two also more complicated
