Description

Technical Field

[0001] The present invention belongs to the technical field of pressure - operated work equipment and relates to a connection and guiding device for a pressure - operated work machine. Background Art

[0002] Currently, pressure - operated work machines are widely used in various constructions of oil and gas exploration and development. As a new technology, the demand for pressure - operated work in the domestic market is continuously expanding. Compared with traditional well - killing operations, it has the advantages of low operation cost and short operation time. Therefore, it is of certain significance to improve the operation efficiency of pressure - operated work, reduce installation time, lower costs, and reduce the labor intensity of workers.

[0003] Small - sized conventional pressure - operated work machines generally adopt integral installation and transportation, which can greatly save non - operation time. However, for large - sized pressure - operated work machines or offshore pressure - operated work equipment, due to the large lifting force of the equipment, large operation space requirements, overweight and over - limit of the equipment, etc., the large - sized pressure - operated work machine cannot adopt an integral structure for whole - machine transportation. To solve the above problems, large - lifting - force pressure - operated work machines generally adopt modular design, and each module can be transported separately and hoisted and installed at the operation site.

[0004] But there are generally two existing installation methods for each module: 1. Ear plates and ear seats are respectively arranged between two modules. During hoisting, it is necessary to align each ear plate with the ear seat and completely drop it into the ear seat before connecting with a pin shaft. 2. Bolts and nuts are used for connection between two modules. The hole positions at the contact part of the two modules need to be completely aligned during hoisting, then bolts are passed through the hole positions and tightened with nuts. The above two methods both require complete alignment during hoisting. Since personnel cannot approach and observe during hoisting, the requirements for hoisting are high and it takes a long time. Summary of the Invention

[0005] The purpose of the present invention is to provide a connection and guiding device for a pressure - operated work machine, which solves the problems of difficult alignment and long time consumption in the connection of ear plates and ear seats in the existing pressure - operated work machine.

[0006] The technical solution adopted by the present invention is that the connection and guiding device for a pressure - operated work machine is used to guide the ear seat of the lifting device and the ear plate of the work platform. A work window is arranged at the bottom of the work platform, and the ear plate is fixed on the work window. The device includes guiding frames fixed on both sides of the lifting device, and guiding columns adapted to the guiding frames are fixed at the bottom of the work window.

[0007] The characteristics of the present invention also lie in that:

[0008] The guiding frame includes a guiding frame body. A first guiding groove is longitudinally formed in the guiding frame body, and the guiding column is located in the first guiding groove. The bottom of the guiding frame body is fixed on the outside of the lifting device.

[0009] Two first guide plates are connected to the top of the guide frame body. The two first guide plates are located on both sides of the first guide groove. A Y-shaped channel is formed between the first guide plates, and the channel communicates with the first guide groove. The first guide plates are inclined away from the lifting device. Second guide plates are vertically connected to both sides of the guide frame body respectively, and an inclined surface is formed at the position where the second guide plates are close to the first guide plates.

[0010] A reinforcing plate is fixed on the side of the guide frame body away from the lifting device. A second guide groove adapted to the first guide groove is formed on the reinforcing plate, and the guide post is located in the first guide groove and the second guide groove at the same time.

[0011] The bottom of the guide frame body is connected to the lifting device through a fixing device.

[0012] The beneficial effects of the present invention are as follows: For the connection guiding device of the pressure-under-operation machine of the present invention, the guide post and the guide frame are used in cooperation for guiding. First, rough guiding is carried out through the first guide plate and the second guide plate, and then precise guiding is achieved through the first guide groove and the second guide groove, which can effectively ensure the rapid and accurate positioning of the ear plate and the ear seat, and meet the rapid installation requirements of the pressure-under-operation machine equipment; the structure is simple and compact, no additional hydraulic operation is required, and it can be repeatedly installed and used for the pressure-under-operation machine.

[0018] The present invention will be described in detail below with reference to the drawings and specific embodiments.

[0019] Embodiment 1

[0020] The connection guiding device of the pressure-under-operation machine, as Figure 1-2As shown, it is used to guide the ear seat 11 of the lifting device 1 and the ear plate 21 of the working platform 2. A working window 22 is provided at the bottom of the working platform 2, and the ear plate 21 is fixed on the working window 22. It includes guide frames 3 fixed on both sides of the lifting device 1, as Figure 3 shown, a guide post 4 adapted to the guide frame 3 is fixed on the bottom frame of the working window 22.

[0021] Embodiment 2

[0022] The connection guiding device of the pressure - operated work machine is used to guide the ear seat 11 of the lifting device 1 and the ear plate 21 of the working platform 2. A working window 22 is provided at the bottom of the working platform 2, and the ear plate 21 is fixed on the working window 22. It includes guide frames 3 fixed on both sides of the lifting device 1, and a guide post 4 adapted to the guide frame 3 is fixed at the bottom of the working window 22.

[0023] As Figure 4 shown, the guide frame 3 includes a guide frame body 301. A first guide groove 302 is longitudinally formed in the guide frame body 301. The guide post 4 is located in the first guide groove 302, and the bottom of the guide frame body 301 is fixed on the outside of the lifting device 1.

[0024] Embodiment 3

[0025] The connection guiding device of the pressure - operated work machine is used to guide the ear seat 11 of the lifting device 1 and the ear plate 21 of the working platform 2. A working window 22 is provided at the bottom of the working platform 2, and the ear plate 21 is fixed on the working window 22. It includes guide frames 3 fixed on both sides of the lifting device 1, and a guide post 4 adapted to the guide frame 3 is fixed at the bottom of the working window 22. Specifically, the bottom of the working window 22 is a square frame structure composed of four square steel pipes 221. Guide posts 4 are respectively fixed on the upper parts of the two side square steel pipes 221. When the working platform 2 is completely lowered in place, the bottom of its square steel pipe 221 contacts the upper surface of the lifting device 1.

[0026] The guide frame 3 includes a guide frame body 301. A first guide groove 302 is longitudinally formed in the guide frame body 301. The guide post 4 is located in the first guide groove 302, and the bottom of the guide frame body 301 is fixed on the outside of the lifting device 1.

[0027] At the top of the guiding frame body 301, two first guiding plates 303 are connected. The two first guiding plates 303 are located on both sides of the first guiding groove 302. A Y-shaped channel 304 is formed between the first guiding plates 303, and the channel 304 communicates with the first guiding groove 302. The first guiding plates 303 are inclined away from the lifting device 1. On both sides of the guiding frame body 301, second guiding plates 308 are vertically connected respectively, and an inclined surface is formed at the position where the second guiding plates 308 are close to the first guiding plates 303. On the side of the guiding frame body 301 away from the lifting device 1, a reinforcing plate 305 is fixed. A second guiding groove 306 adapted to the first guiding groove 302 is formed on the reinforcing plate 305. The guiding column 4 is located in both the first guiding groove 302 and the second guiding groove 306 at the same time. The reinforcing plate 305 further strengthens the guiding frame body 301 to prevent it from being damaged by the working window. The bottom of the guiding frame body 301 is connected to the lifting device 1 through a fixing device 307, and the fixing device 307 is connected to the bottom of the guiding frame body 301 through a pin shaft.

[0028] In this embodiment, the limit dimension tolerance of the second guiding plate 308, the width of the second guiding groove 306 and the dimension tolerance of the guiding column 4 are smaller than the dimension tolerance of the ear plate and the ear seat, so that after the guiding is completed, it can be ensured that the ear plate is located in the middle of the ear seat after the lifting in place.

[0029] The using method of the connection guiding device of the pressure-operated machine of the present invention is as follows:

[0030] When installing the working platform 2, the working platform 2 is lifted by a crane, steel wire rope, etc., and the working platform 2 is hoisted directly above the lifting device 1 in the correct orientation. As the crane is lowered, the bottom of the working window 22 of the working platform 2 gradually approaches the lifting device 1 and the guiding frame 3. Due to slight shaking of the hoisted working platform 2 caused by hoisting or the environment, etc., after the bottom of the working window 22 first contacts the inner side of the first guiding plate 303, it slides downward along the inner inclined surface. Because of contacting the first guiding plate 303, the shaking in the contact surface direction becomes smaller, and at this time, the guiding of the working platform 2 in this direction starts. When the working platform 2 slides downward a certain height, the guiding column 4 starts to contact the guiding frame 3 and enters the channel 304, and at this time, the guiding of the front and rear directions of the working platform 2 starts. The working platform 2 continues to slide along the inclined surface of the second guiding plate 308. When the bottom of the working window 22 finishes sliding along the inclined surface of the second guiding plate 308 and is jointly limited by the two second guiding plates 308 on both sides, the positioning in the left and right directions is completed. At the same time, the guiding column 4 enters the second guiding groove 306 along the channel 304 to complete the positioning in the front and rear directions. At this time, the ear seat 11 is still located above the ear plate 21. After a short distance of vertical lowering, the ear seat 11 can fall into the ear plate 21, the square steel pipe 221 contacts the upper surface of the lifting device 1, and after inserting the pin shaft, the installation of the working platform 2 can be completed.

[0031] In the above manner, the connection and guiding device of the pressure - operated work machine of the present invention saves installation time for the installation of modular pressure - operated work machine equipment, effectively preventing the influence on the alignment installation of the ear plates and ear seats caused by the inability of personnel to approach and observe during the hoisting process and the large swing during high - altitude hoisting, resulting in a long installation time or even damage to the ear plates and ear seats due to the collision of the ear plates and ear seats; by using the cooperation of the guiding columns and the guiding frame for guiding, first rough guiding is carried out through the first guiding plate and the second guiding plate, and then precise guiding is achieved through the first guiding groove and the second guiding groove, which can effectively ensure the rapid and accurate positioning of the ear plates and ear seats, meeting the rapid installation requirements of the pressure - operated work machine equipment; the structure is simple and compact, does not require additional hydraulic operation, and can be repeatedly installed and used for the pressure - operated work machine.
