Abstract
The utility model relates to a piston connector. The utility model is match with the sizes of a pumping piston and a cylinder rod of a pumping oil cylinder. The utility model is characterized in that the utility model is composed of an upper connection body and a lower connection body; both ends of the upper connection body and the lower connection body are respectively provided with an inner rabbet groove and a circular arc surface groove; the upper connection body and the lower connection body are fixed together by a connection member. Simultaneously, the connection end of the pumping piston and the cylinder rod of a pumping oil cylinder is also correspondingly provided with an outer cylindrical surface and a circular arc surface groove. When the upper connection body and the lower connection body are in division part, the inner rabbet groove and a circular arc surface groove are respectively connected with the connection end of the pumping piston and the cylinder rod of a pumping oil cylinder, the upper connection body and the lower connection body are connected into a whole by the connection member, and then the installation work is completed. The connection member can be a bolt with radial installation, and can also be connection members of other types. When the bolt is used as the connection member, the upper connection body and the lower connection body are respectively provided with a through hole and a screw-thread hole. The utility model has the advantages of simple structure, light weight, no need of flange transition, and no need of relative position adjustment. The utility model can finely adjust the coaxiality error between the pumping oil cylinder and the concrete cylinder, and the disassembly and the assembly are completed by one person.
Description
Technical field
The utility model belongs to the concrete conveyer field, relates to a kind of piston joiner of concrete pump.
Background technique
Behind concrete pump work certain hour, often need to change the concrete pumping piston of wearing and tearing.Connect by the piston joiner between pumping piston and the pumping oil cylinder.As shown in Figure 1 linkage structure that at present commonly used is.Piston connector 2 one ends are connected by seam location, bolt with pumping piston 1 in this structure, the other end then also links to each other with pumping oil cylinder cylinder bar 4 with seam location, bolted mode by counter flange 3, this structure is difficult for adjusting to the coaxiality error that produces because of processing, assembling between pumping oil cylinder and concrete cylinder for being rigidly connected.The bolt hole that respectively has one group of confession and pumping piston to be connected on piston connector two end flange with counter flange, one stomidium and another stomidium are concentric, during installation between pumping piston, connector and the counter flange attachment hole must could connect with one heart, and need and will can push concrete cylinder after three's assembling.During dismounting, take off piston connector earlier,, counter flange is connected with pumping piston and pulls it concrete cylinder by the counter flange upper bolt hole.Because the weight heavier (about 25Kg) of pumping piston and connector, and installing space is narrow and small, and is visual poor, and putting above-mentioned three accurately, concentric position assembles comparatively difficulty again, therefore dismounting must two people cooperate just and can finish at least, more very inconvenience in the time of at the construction field (site).
Summary of the invention
The utility model will provide a kind of piston connector of new structure, new structure will be abandoned adpting flange, and can overcome that the connector weight that exists in the prior art is big, installing space is narrow and small, assemble comparatively defective such as difficulty again, finish the connection of piston with lighter weight, reduce the operation requirement of interconnection technique simultaneously, make this work become simple.
The technical solution of the utility model is: piston connector and pumping piston and pumping oil cylinder cylinder unidimensional cooperation of bar, it is characterized in that: constitute by last connecting body and following connecting body two-part, the two ends of upper and lower connecting body respectively are provided with inner stopper groove and arc surface groove, and two connecting bodys are fixed together with link.Simultaneously, the connecting end of pumping piston and pumping oil cylinder cylinder bar is provided with corresponding external cylindrical surface and arc surface groove, two connecting bodys can be when disassembled form, be connected with the connecting end of pumping piston respectively with the arc surface groove with the inner stopper groove with pumping oil cylinder cylinder bar, and then with link that the connection of two connecting bodys is in aggregates, installment work is promptly accused and is finished.Said link can be the bolt of radially installing, and also can be other forms of link.When adopting the bolt of radially installing to connect part, be respectively equipped with through hole and tapped hole on two connecting bodys.Two connecting bodys can whole be processed, and the method with the line cutting is divided into two from the medial axis then, and institute is porose to machine before two connecting bodys are undecomposed.
The piston connector that the utility model provides is simple in structure, and is in light weight, do not need counter flange, also need not adjust relative position.Earlier with pumping oil cylinder cylinder bar piston is headed into concrete cylinder slightly gently during installation, the movable cylinder bar on two piston connector cards, connects (three bolts of for example screwing on) with link again and gets final product behind certain position again.Coaxiality error between fine-tuning pumping oil cylinder of this structure and concrete cylinder, one people can finish during dismounting.
Description of drawings
Fig. 1 is a piston joiner structure schematic representation in the prior art;
Fig. 2 is a connection diagram of the present utility model;
Fig. 3 is the structural drawing of connecting body up and down.
Embodiment
Embodiment 1, with reference to Fig. 2, Fig. 3: be respectively connecting body 5, the two ends of connecting body 6 are provided with the seam groove 7 of internal diameter A1, width C 1 and the inner arc surface groove 8 of width C 2 and circular arc R down, cooperate with pumping piston and pumping oil cylinder cylinder bar respectively.Last connecting body has through hole, and following connecting body has tapped hole, and institute is porose to machine before two connecting bodys are undecomposed.Simultaneously, the connecting end of pumping piston and pumping oil cylinder cylinder bar is provided with corresponding external cylindrical surface and arc surface groove.Two connecting bodys can be when disassembled form, is connected with pumping oil cylinder cylinder bar with pumping piston respectively with the arc surface groove with the inner stopper groove, and then with three groups of radial bolts two connecting bodys is connected and fixed in aggregatesly, and connection work is promptly accused and finished.Because of design gaps, the coaxiality error that arc groove produces in the time of can processing and assemble concrete cylinder, pumping oil cylinder, tank plays the effect of fine setting.Compare with prior art, the utility model is simple in structure, and is in light weight, convenient, fast, time saving and energy saving when installation and removal.
Claims (2)
1, a kind of piston connector, with pumping piston and pumping oil cylinder cylinder unidimensional cooperation of bar, it is characterized in that: be made of last connecting body and following connecting body two-part, the two ends of connecting body respectively are provided with inner stopper groove and arc surface groove up and down, and two connecting bodys are fixed together with link.
2, according to the described piston connector of claim 1, it is characterized in that: said link is the bolt of radially installing, and is respectively equipped with through hole and tapped hole on two connecting bodys.
