Abstract
The invention relates to an assembled concrete mechanical swing mechanism which comprises bolts, a spline shaft, an S elbow and a support and is characterized in that the support with a V-shaped shaft hole is welded on the S elbow; one end of the spline shaft is designed as a V-shaped shaft end matched with the V-shaped shaft hole in size; the V-shaped shaft end of the spline shaft is just mounted on the support with the V-shaped shaft hole; and the spline shaft is fixed on the support by the bolts. The mechanism is convenient to mount, dismount and maintain, and reduces the workload of a user.
Description
Technical field
The present invention relates to a kind of fabricated concreting machinery swing mechanism ，Gai mechanism is installed in concrete pump or jib concrete pump truck hopper.
Background technique
The distributing valve of concrete pump plays a very important role in pumping procedure, and S valve is one of its principal mode, can realize the pumping of high-pressure large-displacement, is also to use at present the widest concrete pumping distributing valve.Its working principle is: the pressure-driven oscillating oil cylinder of hydraulic-pressure pump, oscillating oil cylinder connecting rocker arm, rocking arm connect the splined shaft of S valve, thereby promotes two the working position frequent swings of S pipe in filling the hopper of material, finally realizes concrete continuous conveying.At present, the S pipe assembly of swing mechanism is generally that S pipe is welded into an integral body with splined shaft, and as shown in Figure 1, concrete mode is on S pipe, to weld the bearing that three blocks of shroudings form sealing, axle is through the Kong Bingyu bearing welding on bearing, and recycling stiffening rib is strengthened the connection of bearing and S pipe.
This method can realize the commutation function in concrete pumping process, complete concrete uninterrupted pumping, but this structure makes S pipe become an integral body with splined shaft, when damaging, certain part wherein need change whole S pipe valve, and the manufacture cost of S pipe assembly is very high, with regard to having caused, because of the damage of certain part wherein, cause the loss of scrapping of whole S pipe quite big like this, so need improve its structural design.
Summary of the invention
The problem that object of the present invention exists in order to overcome above-mentioned prior art, and a kind of maintenance, easily dismounting, reliable and stable fabricated concreting machinery swing mechanism be convenient to is provided.
Technological scheme of the present invention is:
A kind of fabricated concreting machinery swing mechanism, comprise bolt, splined shaft, S bend pipe, bearing, it is characterized in that: on described S bend pipe, welding is with the bearing of V-type axis hole, one end of splined shaft is designed to the V-type axle head adapting with described V-type axis hole size, the V-type axle head of splined shaft is just in time arranged on the bearing with V-type axis hole, and splined shaft is bolted on bearing.
The present invention also comprises packing ring, and packing ring is placed on bolt and splined shaft joint.
V-type axis hole on described bearing and the V-type axle head of splined shaft are the laminating of semicircle surface, prevent the front and back play of splined shaft.
Adopt the invention tool of technique scheme to have the following advantages:
1. splined shaft of the present invention can be changed separately, has avoided changing whole S pipe assembly and the waste of the manufacture cost that causes.
2. the present invention, when dismounting splined shaft, can directly lift out very easily in hopper, has reduced dismantlement work amount, has improved maintenance work efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of swing mechanism in prior art.
Fig. 2 is structural representation of the present invention.
Embodiment
The invention will be further described by reference to the accompanying drawings.
At present, the S pipe assembly of swing mechanism is generally that S pipe is welded into an integral body with splined shaft, as shown in Figure 1.Structure of the present invention as shown in Figure 2, comprise bolt 1, packing ring 2, splined shaft 3, S bend pipe 4, bearing 5, it is characterized in that: on described S bend pipe 4, welding is with the bearing 5 of V-type axis hole, one end of splined shaft 3 is designed to the V-type axle head adapting with described V-type axis hole size, the V-type axle head of splined shaft 3 is just in time arranged on the bearing 5 with V-type axis hole, and splined shaft 3 is fixed on bearing 5 by bolt 1, packing ring 2 is placed on bolt 1 and splined shaft 3 joints.V-type axis hole on described bearing 5 and the V-type axle head of splined shaft 3 are the laminating of semicircle surface, prevent the front and back play of splined shaft 3.
By experimental observation, in concrete pump or jib concrete pump truck hopper, the present invention is installed, extremely convenient during component in dismounting, maintenance on swing mechanism, be subject to user's favorable comment.
The present invention is not limited to aforesaid embodiment.The present invention expands to any new feature or any new combination disclosing in this manual, and the arbitrary new method disclosing or step or any new combination of process.
