Description

Technical Field

[0001] The utility model relates to the technical field of hydropower installation engineering, in particular to a pipeline erection device for hydropower installation engineering. Background Art

[0002] Installation projects refer to the installation of various equipment and devices, usually including electrical, ventilation, water supply and drainage, equipment installation and other work content. Industrial equipment and pipelines, cables, lighting lines, etc. are often also covered in the scope of installation projects.

[0003] like Figure 3 As shown, this is a pipe erection device used in the previous generation of hydropower installation projects. Its main function is to fix the auxiliary support of the pipe under the wall top of the building, to perform auxiliary reinforcement on the installed pipe, to prevent the occurrence of problems such as force displacement, shaking, abnormal noise or falling after the pipe is installed, so as to improve the safety of pipe hanging installation and working stability. However, the pipe erection device of this structure has the following shortcomings in actual use: although the vertical position of the hook can be adjusted steplessly by sliding the inner tube in the outer tube, and the hook can be fully adjusted to support and fit the outer wall of the pipe, the inner tube is fixed to the outer tube by means of external stud spiral tightening, which causes the inner tube to slide down in the outer tube when the hook is subjected to vertical impact loads. Over time, it is easy to cause the auxiliary support of the hook to the pipe to fail, thereby affecting the safety and stability of the use of the pipe after installation.

[0004] In view of this, it is particularly important to design and manufacture a pipeline installation device that can enable the hook to stably adjust and fit with the outer wall of the pipeline and improve the safety and stability of the pipeline after installation, and to use it in hydropower installation projects. Utility Model Content

[0005] The purpose of the utility model is to solve the problem that the inner tube of the previous generation of pipeline erection devices for hydropower installation projects is easy to slide down in the outer tube when subjected to impact load, thereby causing the auxiliary support of the hook to the pipeline to fail, and to propose a pipeline erection device for hydropower installation projects.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A pipeline erection device for a hydropower installation project comprises a fixing seat, a mounting hole provided on the fixing seat, an outer cylinder fixed at the lower end of the fixing seat, an inner cylinder movably installed on the inner side of the lower end of the outer cylinder, an outer stud screwed on the lower side of the front end of the outer cylinder and abutting against the inner cylinder through a thread, a first knob installed at the front end of the outer stud, and a hook installed at the lower end of the inner cylinder, wherein a plurality of locking holes for accommodating the rear end of the outer stud are equidistantly provided at the front end of the inner cylinder, and a locking mechanism for assisting pre-tightening operation between an external pipeline and the hook is provided at the lower end of the hook.

[0008] As a further description of the above technical solution:

[0009] The locking mechanism includes a double-headed screw rotatably installed in the middle of the lower end of the hook and with the two ends of the screw arranged in opposite directions, a horizontal slider symmetrically and movably installed in the middle of the lower end of the hook and located on both ends of the double-headed screw, an inner threaded sleeve fixed in the middle of the horizontal slider and matching the double-headed screw, and an inner concave support block movably installed on the inner side of the hook and located between the upper ends of the two horizontal sliders.

[0010] As a further description of the above technical solution:

[0011] The upper ends of the two horizontal sliding blocks are integrally fixedly connected with a transmission bevel block in the shape of a right-angled trapezoidal structure, and the inclined surface of the transmission bevel block faces the concave support block. The left and right ends of the concave support block are provided with transmission bevel grooves for accommodating the transmission bevel block.

[0012] As a further description of the above technical solution:

[0013] The middle parts of the left and right ends of the inner concave support block are fixedly connected with guide columns penetrating the hook piece, and the left and right ends of the hook piece are located on the outer sides of the guide columns and are provided with vertically distributed guide grooves.

[0014] As a further description of the above technical solution:

[0015] A second knob is installed at the right end of the double-headed screw.

[0016] As a further description of the above technical solution:

[0017] The upper end of the hook is integrally fixedly connected with an outer screw seat facing the inner tube, and the inner side of the lower end of the inner tube is provided with an inner screw hole matching the outer screw seat.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0019] In the utility model, by scientifically and rationally improving the original erection device, a plurality of locking holes for accommodating the rear end of the outer stud are arranged on the inner tube, and at the same time, a double-headed screw, a horizontal sliding block and an inner concave support block are arranged on the hook. The outer stud is screwed inwardly into the locking hole at the designated position on the inner tube, so that the preliminary adjustment operation between the hook and the pipeline can be realized. When the second knob is held and turned, under the spiral transmission action between the double-headed screw and the inner thread sleeve and the contact sliding action between the transmission bevel block and the transmission bevel groove, the inner concave support block can slide upward in the hook to fully fit the lower end of the pipeline. This structure enables the hook to fully adjust the support to fit the outer wall of the pipeline, avoiding the occurrence of the problem of failure of the auxiliary support caused by the hook sliding down when the hook is subjected to the vertical impact load, thereby improving the safety and stability of the use of the pipeline after erection.

DETAILED DESCRIPTION

[0025] 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 of 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.

[0026] See also Figure 1-3 The utility model provides a technical solution: a pipeline erection device for a hydropower installation project, comprising a fixing seat 1, a mounting hole 101 opened on the fixing seat 1, an outer tube 2 fixed at the lower end of the fixing seat 1, an inner tube 3 movably installed on the inner side of the lower end of the outer tube 2, an outer stud 5 screwed on the lower side of the front end of the outer tube 2 and abutting against the inner tube 3, a first knob 501 installed at the front end of the outer stud 5 and a hook 4 installed at the lower end of the inner tube 3, a plurality of locking holes 301 for accommodating the rear end of the outer stud 5 are equidistantly opened at the front end of the inner tube 3, and a locking mechanism for assisting pre-tightening operation between the external pipeline and the hook 4 is provided at the lower end of the hook 4.

[0027] Specifically, Figure 1 and Figure 2As shown, the locking mechanism includes a double-headed screw 6 rotatably installed in the middle of the lower end of the hook 4 and with the two ends of the screw arranged in opposite directions, a horizontal slider 7 symmetrically and movably installed in the middle of the lower end of the hook 4 and located on both ends of the double-headed screw 6, an inner threaded sleeve 701 fixed in the middle of the horizontal slider 7 and matching the double-headed screw 6, and a concave support block 8 movably installed on the inner side of the hook 4 and located between the upper ends of the two horizontal sliders 7. The concave part of the concave support block 8 is an isosceles triangle structure, which can fully fit with the outer wall of the pipeline to provide stable auxiliary support for the pipeline, wherein a second knob 601 is installed at the right end of the double-headed screw 6 to facilitate the holding and rotation adjustment operations of the double-headed screw 6.

[0028] The upper ends of the two horizontal sliding blocks 7 are integrally fixedly connected with a transmission bevel block 702 in the shape of a right-angled trapezoidal structure, and the inclined surface of the transmission bevel block 702 faces the inner concave support block 8. The left and right ends of the inner concave support block 8 are provided with a transmission bevel groove 801 for accommodating the transmission bevel block 702. When the transmission bevel block 702 moves horizontally, the transmission bevel block 702 can apply an oblique extrusion force to the transmission bevel groove 801, thereby converting the horizontal movement of the horizontal sliding block 7 into the longitudinal lifting movement of the inner concave support block 8.

[0029] The middle parts of the left and right ends of the inner concave support block 8 are fixedly connected with guide columns 802 that penetrate the hook 4. The left and right ends of the hook 4 are located on the outside of the guide columns 802 and are provided with vertically distributed guide grooves 401. The setting of the guide columns 802 and the guide grooves 401, on the one hand, can stably limit the inner concave support block 8 at the specified position of the hook 4, and on the other hand, improve the stability of the vertical adjustment of the inner concave support block 8 in the hook 4.

[0030] Specifically, Figure 1 and Figure 2 As shown, the upper end of the hook 4 is integrally fixedly connected with an outer screw seat 402 facing the inner tube 3, and the inner side of the lower end of the inner tube 3 is provided with an inner screw hole 302 matching the outer screw seat 402. The arrangement of the outer screw seat 402 and the inner screw hole 302 facilitates the assembly and fixing operation between the hook 4 and the inner tube 3, and also facilitates the adjustment operation of the installation angle of the hook 4 under the inner tube 3.

[0031] Working principle: When using, when installing the pipeline, the first step is to fix the fixing seat 1 in advance through the fasteners and the mounting hole 101 just above the top of the wall where the pipeline is located; the second step is to screw the hook 4 into the inner screw hole 302 of the inner tube 3 through the outer screw seat 402, and then the hook 4 can be assembled and fixed on the inner tube 3, and the inner tube 3 is slid upward into the outer tube 2. After the hook 4 is slid and adjusted to the outside of the pipeline, the first knob 501 is held and turned, and the outer stud 5 is screwed inwardly into the lock hole 301 at the specified position on the inner tube 3, so as to realize the locking operation after the telescopic adjustment between the inner tube 3 and the outer tube 2; the Step three: hold and turn the second knob 601 to operate the double-headed screw 6 to rotate. Under the action of the spiral transmission between the double-headed screw 6 and the inner threaded sleeve 701, the two horizontal sliding blocks 7 can move inward synchronously between the double-headed screw 6 and the hook 4. At this time, the transmission bevel block 702 on the horizontal sliding block 7 can contact and slide in the transmission bevel groove 801 in the concave support block 8, and convert the horizontal displacement movement of the two horizontal sliding blocks 7 into the longitudinal lifting movement of the concave support block 8. When the upper end of the concave support block 8 contacts and squeezes the lower end of the pipe, the pipe fitting is stably supported and fixed in the hook 4, and the auxiliary support operation for the installation of the pipe is completed.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
