Description

Technical Field

[0001] This utility model relates to the field of lifting system technology, and in particular to a lifting device. Background Technology

[0002] Currently, there are many types of lifting equipment, which are widely used in emergency communication, lighting, reconnaissance, meteorology, lightning protection, fire protection and other fields. According to the different usage methods, they can be divided into vehicle-mounted fixed type and ground-mounted type. Among them, vehicle-mounted fixed type is the most widely used, which has the characteristics of convenient use, high mobility and good concealment.

[0003] Vehicle-mounted fixed type means that the lifting equipment is installed and fixed on the vehicle. When working, the vehicle is parked at a certain point, and the antenna, turntable and other equipment on the top of the lifting equipment are raised to the required height. After the equipment completes communication and other work, the antenna, turntable and other equipment are retracted to the stored state. Due to the limitations of highway tunnels, the closed height of the lifting equipment needs to be minimized as much as possible. However, when the lifting equipment is deployed, the deployed height needs to be increased as much as possible. The higher the deployed height, the higher the closed height of the lifting equipment gradually becomes, which cannot meet the requirements of vehicle-mounted use of the lifting equipment. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the present invention provides a lifting device that solves the problem that existing lifting devices cannot reach a high height to meet the needs of vehicle use.

[0005] According to the embodiments of this utility model, the following technical solution is adopted:

[0006] A lifting device, comprising:

[0007] Automatic telescopic poles and manual telescopic poles;

[0008] A connecting plate has a first mounting surface and a second mounting surface on the same plane.

[0009] A limiting component is located at one end of the connecting plate and is snapped into the fixing part of the manual telescopic rod to limit the movement of the manual telescopic rod.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] In this solution, automatic and manual telescopic poles are connected in series, allowing them to rise and fall simultaneously during operation, meeting the requirements for high-altitude use. The automatic and manual telescopic poles are mounted on the same connecting plate. When the automatic pole lowers the connecting plate, the connecting plate synchronously lowers the manual pole, causing its telescopic section to gradually retract to the position of the connecting plate. This design features high deployment and low closure, facilitating transportation while also meeting the requirements for high-altitude equipment use.

[0023] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0024] like Figures 1 to 3 As shown in the figure, this utility model embodiment proposes a lifting device, including:

[0025] Automatic telescopic pole 1 and manual telescopic pole 2;

[0026] The connecting plate 3 has a first mounting surface and a second mounting surface on the same plane. One end of the telescopic part of the automatic telescopic rod 1 is located on the first mounting surface, and the fixing part of the manual telescopic rod 2 is located on the second mounting surface. The second mounting surface also has a through hole 304 through which the telescopic part of the manual telescopic rod 2 passes, and the wire rope 7 of the manual telescopic rod 2 is connected to the telescopic part of the automatic telescopic rod 1.

[0027] A limiting component is provided at one end of the connecting plate 3 and is snapped into the fixing part of the manual telescopic rod 2 to limit the movement of the manual telescopic rod 2.

[0028] In the embodiments of this utility model, the automatic telescopic rod 1 can be any type of telescopic mechanism, such as an electric rod or a hydraulic rod. The manual telescopic rod 2 is a wire rope linkage lifting rod, which is a lifting method. In the initial assembly of the automatic telescopic rod 1 and the manual telescopic rod 2, the wire rope 7 used for lifting is connected to the telescopic part of the automatic telescopic rod 1. The telescopic part of the automatic telescopic rod 1 can be any telescopic tube except the top section. Figure 1 For example, the wire rope 7 is connected to the edge of the secondary top section tube. The connection method includes, but is not limited to, welding. Then, one end of the telescopic part of the automatic telescopic rod 1 (the end of the top section tube) is installed at the bottom of the first mounting surface. The connection method includes, but is not limited to, welding. In this connection method, when the telescopic part of the automatic telescopic rod 1 is extended, it can drive the connecting plate 3 to rise as a whole. The fixed part of the manual telescopic rod 2 (i.e., the bottom section tube) is installed at the bottom of the second mounting surface and can move with the connecting plate 3.

[0029] During operation, activating the automatic telescopic pole 1 causes its telescopic tubes to expand relative to each other, increasing its overall height. This expansion of the telescopic tubes also stretches the steel wire rope 7, which in turn drives the telescopic tubes of the manual telescopic pole 2 to expand, achieving synchronous raising of both the automatic and manual telescopic poles and creating a relay-lift effect. This allows the equipment on the manual telescopic pole 2 to be quickly deployed to the required height. During descent, the telescopic tubes of the automatic telescopic pole 1 retract, causing the connecting plate 3 to descend. The retraction of the tubes also causes the steel wire rope 7 to retract, allowing the manual telescopic pole 2 to shorten itself while following the descent of the connecting plate 3, thus retracting to one side of the automatic telescopic pole 1 and ensuring the final closed height.

[0030] Based on the above solutions, such as Figure 3 As shown, the limiting component includes a fixing plate 4 fixedly connected to the end of the connecting plate 3 and a mounting bracket 8 provided on the fixing plate 4. Two limiting blocks 5 are provided on the side of the mounting bracket 8, and the fixing part of the manual telescopic rod 2 is located between the two limiting blocks 5.

[0031] To ensure the stability of the connection and prevent shaking after unfolding, the connection area between the connecting plate 3 and the manual telescopic rod 2 can be increased by the action of the fixing plate 4, the mounting bracket 8 and the two limiting blocks 5, thereby ensuring the stability of the fixed part of the manual telescopic rod 2 on the connecting plate 3 after unfolding.

[0032] Specifically, the mounting bracket 8 is rotatably equipped with a bidirectional screw 6, and two transmission blocks 601 are correspondingly inserted through the mounting bracket 8. The two transmission blocks 601 are threaded to both ends of the bidirectional screw 6 and connected to two limiting blocks 5 respectively. To facilitate the initial installation of the manual telescopic rod 2, the distance between the two limiting blocks 5 needs to be greater than the diameter of the manual telescopic rod 2. After the manual telescopic rod 2 is installed on the connecting plate 3 from bottom to top, the bidirectional screw 6 can be rotated to drive the two transmission blocks 601 closer to each other, so that the two limiting blocks 5 abut against the manual telescopic rod 2, providing lateral positioning and support for the manual telescopic rod 2 and ensuring the stability of the manual telescopic rod 2 at a high position. Moreover, the limiting blocks 5 have arc-shaped grooves 501. When the limiting blocks 5 abut against the manual telescopic rod 2, the arc-shaped grooves 501 engage with the arc-shaped surface of the manual telescopic rod 2, indirectly providing multi-directional limiting support for the manual telescopic rod 2.

[0033] Secondly, a sliding groove 401 is provided on the side of the fixing plate 4, and the mounting bracket 8 is slidably engaged with the sliding groove 401; this allows the mounting bracket 8 to slide on the fixing plate 4, making it suitable for manual telescopic rods 2 of different lengths. Furthermore, a knob 602 is provided at one end of the bidirectional screw 6, and the knob 602 has several anti-slip grooves, facilitating manual adjustment of the bidirectional screw 6 without the need for other adjustment tools. The anti-slip grooves also increase friction with the palm, improving the ease of adjustment.

[0034] Specifically, such as Figure 3 As shown, fastening screws 303 are provided on both the first and second mounting surfaces. Several fastening screws 303 are respectively connected to the fixing part of the manual telescopic rod 2 and one end of the telescopic part of the automatic telescopic rod 1. In order to facilitate the installation and subsequent maintenance of the manual telescopic rod 2 and the automatic telescopic rod 1, the fastening screws 303 can be used to complete the assembly quickly. Afterwards, the manual telescopic rod 2 and the automatic telescopic rod 1 can be disassembled simply by removing the fastening screws 303, without causing damage to either of them.

[0035] Furthermore, the other end of the connecting plate 3 is bent upward to form a bending portion 301. The bending portion 301 is provided with a reinforcing rib 302, which is connected to the first mounting surface and the second mounting surface. Since one end of the connecting plate 3 needs to bear the entire weight of the manual telescopic rod 2 and the tension of the wire rope 7, the overall strength of the connecting plate 3 is increased by the cooperation of the reinforcing rib 302 and the bending portion 301, which prevents the connecting plate 3 from deforming during long-term use and indirectly improves its service life.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
