Description

TECHNICAL FIELD

[0001] The utility model relates to municipal engineering car technical field, concretely relates to a lifting guide rail rotation structure. BACKGROUND

[0002] In engineering construction, especially in the installation, maintenance or drilling and piling operation of highway guardrails, it is often necessary to position the lifting guide rail to a specific height and angle. The traditional lifting guide rail structure can only realize simple lifting function, and cannot meet the flexible adjustment demand of the direction of the lifting guide rail, which limits the construction efficiency and operation range to some extent. Especially in the case of uneven or inclined ground, the traditional lifting guide rail structure is more difficult to ensure the stability and accuracy of the operation. At the same time, the traditional lifting guide rail cannot adjust the direction, and can only be stacked above the transverse guide rail after being adjusted to the horizontal state. Because the lifting guide rail is long, it increases the overall width of the vehicle body, which has safety hazards in the transportation process. SUMMARY

[0003] In view of the above technical deficiencies, the utility model aims at providing a lifting guide rail rotation structure which can adjust the inclination angle and direction of the lifting guide rail and is convenient for construction.

[0004] To solve the above technical problems, the utility model adopts the following technical scheme: the utility model provides a lifting guide rail rotation structure, which comprises:

[0005] A slewing bearing is fixed at the end of the transverse guide rail, a mounting plate is fixed on the slewing bearing, a first hinge seat and a second hinge seat are fixed on the mounting plate;

[0006] A connecting frame is fixed on the lifting guide rail, one end of the connecting frame is hinged to the first hinge seat, and the other end is fixed with a third hinge seat;

[0007] A hydraulic cylinder is hinged to the second hinge seat at one end and to the third hinge seat at the other end.

[0008] Preferably, the first hinge shaft on the first hinge seat is located on the mounting plate outside the projection range of the slewing bearing on the mounting plate.

[0009] Preferably, the second hinge shaft on the second hinge seat is located on the mounting plate inside the projection range of the slewing bearing on the mounting plate.

[0010] Preferably, the slewing bearing comprises an inner ring and an outer ring, the outer ring is rotatably installed on the inner ring, the inner ring is fixedly connected with the transverse guide rail, and the mounting plate is fixedly connected with the outer ring.

[0011] Preferably, a worm gear is fixed on the outer ring, and a worm that meshes with the worm gear is provided on the transverse guide rail.

[0012] Preferably, a hydraulic motor for driving the worm gear rotation is fixed on the transverse guide rail.

[0013] The beneficial effects of this utility model are as follows:

[0014] This invention, through the design of components such as a slewing bearing, a connecting frame, and a hydraulic cylinder, allows the hydraulic cylinder to adjust the tilt angle of the lifting guide rail, while the slewing bearing adjusts the orientation of the lifting guide rail. This enables flexible rotation and precise angle adjustment of the lifting guide rail relative to the transverse guide rail, allowing it to easily face any desired direction. Especially under conditions of sloping ground or complex terrain, it ensures the precise vertical positioning of construction equipment or tools, greatly improving construction efficiency and adaptability to the work area. Since the lifting guide rail can rotate on the slewing bearing, it can be stored perpendicular to the transverse guide rail on the side of the construction vehicle for easy transport. Through a reasonable structural design, when the connecting frame rotates around the hinge axis of the first hinge seat, the connecting frame and the lifting guide rail can rotate to a range outside the slewing bearing without interfering with it. Simultaneously, the structure of the hydraulic cylinder and the connecting frame is more compact, ensuring the stability and balanced force distribution of the lifting guide rail during rotation. This helps extend the service life of the structure, reduces malfunctions and damage caused by uneven force distribution, and improves construction safety. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1:

[0025] like Figures 1 to 5 As shown, Embodiment 1 of this utility model provides a rotating structure for the lifting guide rail 5, which enables the lifting guide rail 5 to rotate and adjust its angle relative to the transverse guide rail 1, thereby allowing the lifting guide rail 5 to more easily face the guardrail. Figure 1 As shown, the rotating structure of the lifting guide rail 5 designed in this utility model specifically includes a slewing bearing 3, a connecting frame 4, and a hydraulic cylinder 8, etc. The detailed implementation method is as follows:

[0026] First, a slewing bearing 3 is fixedly installed on the end of the transverse guide rail 1 near the highway guardrail. The slewing bearing 3 is a large bearing capable of bearing longitudinal loads, also known as a slewing bearing or rotary bearing, and typically consists of an inner ring, an outer ring, and rolling elements. The inner and outer rings serve as the inner and outer support parts of the bearing, respectively, while the rolling elements are located between the inner and outer rings to transmit and bear the load. In this design, the inner ring of the slewing bearing 3 is fixedly installed on the transverse guide rail 1, while a mounting plate 2 is fixed to the outer ring.

[0027] like Figure 2As shown, mounting plate 2 serves as the base for connecting other components. Two hinge seats, namely the first hinge seat 6 and the second hinge seat 7, are fixed on this mounting plate 2. The lifting guide rail 5 is fixed to a connecting frame 4, which can be fixed to the lifting guide rail 5 by welding or bolting. One end of the connecting frame 4 is connected to the first hinge shaft 11 on the first hinge seat 6 by a hinge, ensuring that the connecting frame 4 can swing relative to the first hinge seat 6. The other end of the connecting frame 4 is fixed to a third hinge seat 9, which will be used to connect to the hydraulic cylinder 8.

[0028] Hydraulic cylinder 8 serves as the driving component, with one end hinged to the second hinge shaft 12 of the second hinge seat 7 and the other end hinged to the third hinge shaft 13 of the third hinge seat 9. The extension and retraction of hydraulic cylinder 8 drives the connecting frame 4 to rotate around the first hinge shaft 11 on the first hinge seat 6, thereby rotating the lifting guide rail 5 and allowing it to rotate from a horizontal to a vertical position. The slewing bearing 3 allows the mounting plate 2 to rotate on the transverse guide rail 1, thus adjusting the orientation of the lifting guide rail 5. This enables the lifting guide rail 5 to be adjusted to a vertical position even when the ground is tilted, facilitating drilling or piling in the vertical direction.

[0029] like Figure 4 As shown, the lifting guide rail 5 can be adjusted to be perpendicular to the transverse guide rail 1. In this way, the lifting guide rail 5 can be folded up to the side of the engineering vehicle without exceeding the width of the vehicle body, thus facilitating transportation.

[0030] Example 2:

[0031] Based on Embodiment 1, this utility model has carefully designed the positional layout of the first hinge seat 6 and the second hinge seat 7: as follows Figure 3 and Figure 5 As shown, the hinge axis of the first hinge seat 6 is located outside the projection range of the slewing bearing 3 on the mounting plate 2, that is... Figure 3 The portion outside the two dashed lines; while the hinge axis of the second hinge seat 7 is located inside the projection range, that is, within the two dashed lines. In this way, when the connecting frame 4 rotates around the hinge axis of the first hinge seat 6, the connecting frame 4 and the lifting guide rail 5 can rotate to a range outside the slewing bearing 3, without interfering with the slewing bearing 3. At the same time, it makes the structure of the hydraulic cylinder 8 and the connecting frame 4 more compact, which helps to optimize the stability and stress distribution of the overall structure.

[0032] Example 3:

[0033] Based on Embodiments 1 and 2, to further enhance the controllability of the structure, a worm gear is fixed on the outer ring of the slewing bearing 3, and a hydraulic motor 10 is fixedly connected to the transverse guide rail 1. A worm gear meshing with the worm gear is provided on the output shaft of the hydraulic motor 10. Through the cooperation of the worm gear and the worm wheel, the rotation of the slewing bearing 3 can be precisely controlled by the hydraulic motor 10, which facilitates the adjustment of the orientation of the lifting guide rail 5 to adapt to the current position of the highway guardrail.

[0034] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
