Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, and in particular to a column structure for climbing equipment used in high slope construction. Background Technology

[0002] In hydropower stations, high slopes are typically reinforced with multiple prestressed anchor cables or bolts to enhance the stability of the surrounding rock. Existing equipment generally uses telescopic booms, with drilling and other working mechanisms located at the end of the boom. However, this working platform, which houses the drilling and anchor cable installation mechanisms as well as the auxiliary boom, is very heavy. Furthermore, due to the narrow access roads on high hydropower slopes, typically 3 to 5 meters wide, the boom cannot extend directly towards the slope and must extend laterally. This requires an even longer boom extension. The reaction forces generated during drilling and cable delivery also act laterally on the boom, demanding high boom rigidity. Consequently, the boom's cross-sectional dimensions and weight become very large, ultimately resulting in equipment that is too large to operate on narrow access roads.

[0003] Currently, there is no dedicated construction equipment for anchor cable drilling and installation. The process is mainly carried out manually by building scaffolds, mounting the drilling equipment on the scaffolds, and having workers stand on the scaffolds to manually install the anchor cables. This method has many disadvantages, including a large number of construction workers, high labor intensity, low work efficiency, and poor safety.

[0004] Therefore, mechanized construction is the fundamental solution to this problem. In view of this, a new technical solution is needed to address the aforementioned technical issues. Utility Model Content

[0005] The purpose of this utility model is to provide a column structure for climbing equipment in high slope construction, so as to solve the problems of difficult high slope construction in the prior art.

[0006] To achieve the above objectives, the present invention employs the following technical means:

[0007] A column structure for climbing equipment in high slope construction is mounted on a trolley. It includes a basic section, a column, an angle adjustment device, a support device, and a tie rod device. One end of the basic section is hinged to the trolley chassis, and the lower part of the column is hinged to the other end of the basic section and can rotate around the hinge point. One end of the angle adjustment device is hinged to the trolley chassis, and the other end is hinged to the basic section. The extension and retraction of the angle adjustment device drives the basic section to rotate around the hinge point of the trolley chassis. One end of the support device is located on the side of the column, and the other end is located on the high slope and is extendable and retractable. The tie rod device connects the column and the access road to the high slope and allows for distance adjustment.

[0008] This utility model mounts the column structure on a trolley chassis. The column is assembled from a basic section and multiple modular first and second columns fixed together with bolts. When working, the column unfolds facing the high slope and can support the high slope. The working platform can rise or fall along the column to the required construction position via a transmission mechanism. The column can adapt to high slopes of different heights by adding or removing standardized first and second columns. The column can be extended and retracted by an angle adjustment device hinged to the trolley chassis, allowing the column to pitch at different angles to meet the needs of high slopes of different gradients.

[0009] As a further improvement, the support column includes a first support column and a second support column. The lower part of the first support column is hinged to the other end of the basic section and can rotate around the hinge point. The second support column is hinged to the upper part of the first support column and can be rotated and folded to be placed parallel to the side of the first support column. The first and second support columns are manufactured modularly and can be referred to as standard sections. The design is not limited to a combination of two first and second support columns; it can be a combination of multiple first and second support columns.

[0010] As a further improvement, the basic section is equipped with a first slide rail, a first carriage, and a first adjusting cylinder. The other end of the first carriage is mounted on the first column. Under the action of the first adjusting cylinder, the first carriage moves along the first slide rail, simultaneously causing the first column to move relative to the basic section and disengage from the basic section. The first column is equipped with a second slide rail, a second carriage, a second adjusting cylinder, and a pin. The other end of the second carriage is mounted on the second column. Under the action of the second adjusting cylinder, the second carriage moves along the second slide rail, simultaneously causing the second column to move relative to the first column and disengage from the first column. After the second column rotates relative to the first column and becomes flush with the first column, the pin is inserted between the second column and the first column for fixation.

[0011] As a further improvement, a working platform is installed on the first column, and a transmission mechanism is connected between the working platform and the first column. The working platform is raised and lowered along the first column and the second column by the transmission mechanism.

[0012] As a further improvement, the support device includes an outer sleeve, an inner sleeve, and a support plate. The outer sleeve is fixed to the column, one end of the inner sleeve is fitted onto the outer sleeve, and the support plate is installed at the other end of the inner sleeve. The inner sleeve can extend and retract relative to the outer sleeve, and the support plate is installed on a high slope.

[0013] As a further improvement, the support device also includes a strut, one end of which is connected to the column and the other end of which is connected to the outer casing.

[0014] As a further improvement, the tie rod device includes a first threaded tie rod, a second threaded tie rod, a fixed rod, an internal threaded connecting sleeve, and a force-applying rod. The fixed rod is installed on the access road of the high slope. The first threaded tie rod and the second threaded tie rod are threadedly connected to the internal threaded connecting sleeve. The other end of the first threaded tie rod is connected to the fixed rod, and the other end of the second threaded tie rod is connected to the column. The force-applying rod is inserted into the internal threaded connecting sleeve and rotated to adjust the distance between the first threaded tie rod and the second threaded tie rod.

[0015] As a further improvement, a first connecting seat is provided between the first threaded tie rod and the fixed rod, and a second connecting seat is provided between the second threaded tie rod and the column.

[0016] Compared with the prior art, this utility model brings the following technical effects:

[0017] This utility model mounts the column structure on a trolley chassis. The column is assembled from a basic section and multiple modular first and second columns, which are fixed together by bolts. When in operation, the column unfolds facing the high slope and can support the slope. The work platform can be raised or lowered to the required construction position along the column via a transmission mechanism. The column can adapt to high slopes of different heights by adding or removing standardized first and second columns. The column can be extended and retracted by an angle adjustment device hinged to the trolley chassis, allowing the column to tilt at different angles to meet the needs of high slopes of different gradients. When not in use and during travel, the column structure can be folded down in front of the trolley to reduce its length. At the same time, the work platform can be lowered to the bottom of the column for easy travel on narrow slopes. Attached Figure Description

The tie rod device connects the column and the access road to the high slope and allows for distance adjustment.

[0030] This utility model mounts the column structure on a trolley chassis.

When in operation, the column unfolds facing the high slope and can support the slope. The work platform can be raised or lowered to the required construction position along the column via a transmission mechanism.

[0031] Example

[0032] Please see Figures 1 to 3 This utility model provides a column structure (hereinafter referred to as "column structure") 100 for climbing equipment in high slope construction, mounted on a trolley 200, for construction of a high slope 300. The column structure 100 includes a basic section 1, a column, an angle adjustment device 3, a support device 4, and a tie rod device 5. One end of the basic section 1 is hinged to the chassis of the trolley 200, and the lower part of the column is hinged to the other end of the basic section 1 and can rotate around the hinge point. One end of the angle adjustment device 3 is hinged to the chassis of the trolley 200, and the other end is hinged to the basic section 1. The extension and retraction of the angle adjustment device 3 drives the basic section 1 to rotate around the hinge point of the trolley 200 chassis. Preferably, the angle adjustment device 3 is a pitch cylinder. One end of the support device 4 is located on the side of the column, and the other end is located on the high slope 300 and is extendable and retractable. The tie rod device 5 is used to connect the column and the access road 301 of the high slope 300 and to achieve distance adjustment.

[0033] For more details, please refer to Figure 2 and Figure 3The column includes a first column 2 and a second column 6. The lower part of the first column 2 is hinged to the other end of the basic section 1 and can rotate around the hinge point. The second column 6 is hinged to the upper part of the first column 2 and can be rotated and folded to be placed parallel to the side of the first column 2. It can be understood that the column includes at least the interconnected first column 2 and second column 6, and may also include multiple first columns 2 and second columns 6, modularly setting the first columns 2 and second columns 6, increasing or decreasing the number of columns according to different needs.

[0034] When using this utility model, please refer to [link / reference]. Figure 1 The trolley 200 is positioned on the dismounting ramp 302 of the high slope. The basic section 1, the first column 2, and the second column 6 are all fully extended into a straight line and fixed to form an integral column. The basic section 1 is hinged to the chassis of the trolley 200. Under the action of the angle adjustment device 3, the integral column falls towards the high slope 300. After the angle of the integral column falls is approximately the same as the angle of the high slope 300, the support device 4 extends and supports the high slope 300. A tie rod device 5 is arranged on the ascending ramp 301 of the high slope 300, and the second column 6 is fixed to the ascending ramp 301 of the high slope 300 via the tie rod device 5. The integral column is supported by the support device 4 against the high slope 300, which can make the integral column have good rigidity and small deformation. At the same time, the top of the integral column is fixed to the access road 301 of the high slope 300 by the tie rod device 5, which can reduce the reaction force on the integral column during drilling and increase the overturning moment of the trolley 200, thereby increasing the overturning safety factor of the equipment.

[0035] For more details, please refer to Figure 2 and Figure 3 The basic section 1 is equipped with a first slide rail 11, a first slide 12, a first adjusting cylinder 13 and an angle adjusting cylinder 14. The other end of the first slide 12 is mounted on the first column 2. The first slide 12 moves along the first slide rail 11 under the action of the first adjusting cylinder 13, and at the same time drives the first column 2 to move relative to the basic section 1 and disengage from the basic section 1. Then, under the action of the angle adjusting cylinder 14, the first column 2 rotates and falls down relative to the basic section 1 along the hinge point.

[0036] For more details, please refer to Figure 3 and Figure 4 The first column 2 is equipped with a second slide rail 21, a second slide bracket 22, a second adjusting cylinder 23 and a pin 24. The other end of the second slide bracket 22 is mounted on the second column 6. The second slide bracket 22 moves along the second slide rail 21 under the action of the second adjusting cylinder 23, and at the same time drives the second column 6 to move relative to the first column 2 and separate from the first column 2. After the second column 6 rotates relative to the first column 2 and becomes flush with the first column 2, the pin is inserted between the second column 6 and the first column 2 for fixation.

[0037] For more details, please refer to Figure 1 and Figure 5 The first column 2 is equipped with a working platform 7. The working platform 7 is connected to the first column 2 by a transmission mechanism (not shown in the figure). The working platform 7 is raised and lowered along the first column 2 and the second column 6 by the transmission mechanism, so as to realize the operation and construction at different positions on the high slope 300.

[0038] When not in use, the working platform 7 is lowered to the bottom when the trolley 200 is in motion, and the entire column is folded down, so that the entire column can be hinged to the front end of the trolley 200 like a boom. At the same time, the length is short, which makes it convenient to transport with the vehicle without disassembling it.

[0039] For more details, please refer to Figure 1 and Figure 6 The support device 4 includes an outer sleeve 41, an inner sleeve 42, a support plate 43, and a strut 44. The outer sleeve 41 is fixed to the first column 2 or the second column 6. This invention is illustrated by fixing the outer sleeve 41 to the second column 6. One end of the inner sleeve 42 is fitted onto the outer sleeve 41, and the support plate 43 is installed at the other end of the inner sleeve 42. The inner sleeve 42 can extend and retract relative to the outer sleeve 41. The support plate 43 is positioned on the high slope 300. The support device 4 can stably and reliably support the rock surface of the high slope 300, enhancing the rigidity of the column and preventing deformation. The support plate 43, being extendable and retractable along with the inner sleeve 42, adapts well to the uneven terrain of the high slope 300 and reliably supports the surrounding rock. Furthermore, the number of support devices 4 can be appropriately increased according to the overall length of the column to enhance the overall rigidity of the column and prevent deformation. Preferably, one end of the support rod 44 is connected to the second column 6, and the other end of the support rod 44 is connected to the outer casing 41. The support rod 44 can strengthen the outer casing 41.

[0040] For more details, please refer to Figure 1 and Figure 7 The tie rod device 5 includes a first threaded tie rod 51, a second threaded tie rod 52, a fixed rod 53, an internally threaded connecting sleeve 54, and a force-applying rod 55. The fixed rod 53 is installed on the access road 301 of the high slope 300. The first threaded tie rod 51 and the second threaded tie rod 52 are threadedly connected to the internally threaded connecting sleeve 54. The other end of the first threaded tie rod 51 is connected to the fixed rod 53, and the other end of the second threaded tie rod 52 is connected to the second column 6. The force-applying rod 55 is inserted into the internally threaded connecting sleeve 54 and rotated to adjust the distance between the first threaded tie rod 51 and the second threaded tie rod 52. Preferably, a first connecting seat 56 is provided between the first threaded tie rod 51 and the fixed rod 53, and a second connecting seat 57 is provided between the second threaded tie rod 52 and the second column 6.

[0041] In use, the tie rod device 5 of this utility model has the top rod 53 inserted and fixed in a pre-drilled hole in the access road 301 of the high slope 300. One end of the first connecting seat 56 is connected to the fixed rod 53, and the other end of the first connecting seat 56 is connected to the first threaded tie rod 51. One end of the second connecting seat 57 is connected to the first column 2 or the second column 6, and the other end of the second connecting seat 57 is connected to the second threaded tie rod 52.
