Description

Technical Field

[0001] The utility model relates to the technical field of connecting pieces, in particular to a connecting piece for a mud pump. Background Art

[0002] A mud pump is a machine that delivers mud or flushing fluids such as water to the borehole during the drilling process. During the mud pumping process, a connecting pipe for discharging mud needs to be connected to the output end. However, most existing mud pumps are directly connected to the connecting pipe through a flange. However, since the medium transported inside the connecting pipe is mud, the connecting pipe is prone to blockage and needs to be frequently disassembled and maintained. The connecting pipe connected through a flange is inconvenient to disassemble and assemble. Utility Model Content

[0003] The purpose of the utility model is to provide a connecting piece for a mud pump to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a connecting piece for a mud pump, comprising a fixed pipe and a connecting pipe, the connecting pipe is sleeved on the pipe wall at one end of the fixed pipe, and a first hoop frame and a second hoop frame are sleeved on the outer pipe wall of the connecting pipe sleeved on the fixed pipe, a first stroke groove is opened on the first hoop frame corresponding to the second hoop frame, a second stroke groove is opened on the second hoop frame corresponding to the first hoop frame, the first hoop frame and the second hoop frame are connected through the first stroke groove and the second stroke groove, one end of the first hoop frame extending to the inside of the second hoop frame and one end of the second hoop frame extending to the inside of the first hoop frame are both provided with springs, and the other ends of the two springs are respectively connected to the inner walls of the adjacent first hoop frame and the second hoop frame.

[0005] Preferably, a flange is provided at one end of the fixing pipe away from the connecting pipe.

[0006] Preferably, ends of the first hoop frame and the second hoop frame that are away from each other are both threadedly connected with a screw rod, and the end of the screw rod is fixedly connected with a toggle block.

[0007] Compared with the prior art, the beneficial effects of the utility model are as follows: the utility model is a connecting piece for a mud pump with a simple structure and is easy to use. The fixed pipe is connected to the output end of the mud pump through a flange to replace the connecting pipe, and the connecting pipe can be connected to the end of the fixed pipe through the first hoop frame and the second hoop frame. The first hoop frame and the second hoop frame are locked and clamped by a spring and a screw rod, which makes it more convenient to disassemble and assemble the connecting pipe from the fixed pipe.

[0013] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0014] See also Figures 1 - 4 The utility model provides a technical solution: a connecting piece for a mud pump, comprising a fixed pipe 1 and a connecting pipe 3, the connecting pipe 3 is sleeved on the pipe wall at one end of the fixed pipe 1, and a first hoop frame 4 and a second hoop frame 5 are sleeved on the outer pipe wall of the connecting pipe 3 sleeved on the fixed pipe 1, a first stroke groove 6 is opened on the first hoop frame 4 corresponding to the second hoop frame 5, and a second stroke groove 7 is opened on the second hoop frame 5 corresponding to the first hoop frame 4, the first hoop frame 4 and the second hoop frame 5 are connected through the first stroke groove 6 and the second stroke groove 7, one end of the first hoop frame 4 extending to the inside of the second hoop frame 5 and one end of the second hoop frame 5 extending to the inside of the first hoop frame 4 are both provided with a spring 8, and the other ends of the two springs 8 are respectively connected to the inner walls of the adjacent first hoop frame 4 and the second hoop frame 5.

[0015] A flange 2 is provided at one end of the fixed pipe 1 away from the connecting pipe 3, and the flange 2 enables the fixed pipe 1 to be conveniently connected to the output end of the mud pump.

[0016] The ends of the first hoop frame 4 and the second hoop frame 5 that are away from each other are both threadedly connected with a screw rod 10. The setting of the screw rod 10 can effectively lock and limit the first hoop frame 4 and the second hoop frame 5. The end of the screw rod 10 is fixedly connected with a toggle block, which can effectively make the screw rod 10 more convenient and labor-saving when rotating.

[0017] Specifically, in the initial state, the fixed pipe 1 is connected to the output end of the mud pump instead of the connecting pipe 3 by passing the bolts through the flange 2. Since the fixed pipe 1 is short in length, it can avoid clogging with a greater probability.

[0018] When in use, the first hoop 4 and the second hoop 5 are pushed towards the adjacent direction, so that the first hoop 4 and the second hoop 5 move towards each other against the elastic force of the spring 8, and the length of the through groove between the first hoop 4 and the second hoop 5 is increased, so as to facilitate passing the connecting pipe 3 through the first hoop 4 and the second hoop 5 and sleeving it on the outer pipe wall of the fixed pipe 1. At this time, the pushing of the first hoop 4 and the second hoop 5 is released, and the first hoop 4 and the second hoop 5 can be pre-clamped on the outer wall of the connecting pipe 3 under the action of the elastic force of the spring 8. Finally, by tightening the screw rod 9, the connecting pipe 3 can be stably sleeved on the fixed pipe 1 through the first hoop 4 and the second hoop 5.

[0019] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
