In addition, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0025] Figure 1 The structural schematic diagram of a new type of retractable gin pole is shown. Aiming at the problems existing in the prior art in the background art, such as Figure 1 As shown, the embodiment of the present application provides a new type of retractable gin pole, including: a telescopic first support rod 1, a base 2 connected to the lower end of the first support rod 1, a connecting piece 3 connected to the upper end of the first support rod 1, and a cross bar 4 connected between the two first support rods 1. Among them, the two first support rods 1 are connected to both sides of the connecting piece 3 in a "person" shape through a hinge; it is characterized in that it further includes a limit support mechanism 5 horizontally connected to the lower part of the first support rod 1. The limit support mechanism 5 includes a second support rod 51, a fixed block 52 connected to the front end of the second support rod 51, a telescopic mechanism 53 connected to the fixed block 52, and a support block 54 installed at the front end of the telescopic mechanism 53; among them, the two second support rods 51 are connected to both sides of the fixed block 52 in a "person" shape through a hinge.

[0026] Specifically, in this embodiment, the connecting piece 3 is located at the upper ends of the two first support rods 1, and the tops of the two first support rods 1 are respectively connected to both sides of the connecting piece 3 in a hinged manner, so as to form a "person" shape structure. Optionally, the connecting piece 3 is also provided with hooks, mounting holes or grooves for fixing pulley groups and other auxiliary equipment. The limit support mechanism 5 is horizontally connected to the lower parts of the two first support rods 1, and provides a horizontal support force for the facility to be erected through the support block 54. The telescopic mechanism 53 adjusts the telescopic length to change the horizontal position of the support block 54 so that it adapts to the distance between the facility to be erected and the installation position. The connection method of the second support rod 51 and the fixed block 52 refers to the connection method of the first support rod 1 and the connecting piece 3, which will not be elaborated here.

[0027] Preferably, the first support rod 1 is made of carbon fiber material to ensure that the new retractable A-frame pole has sufficient load-bearing capacity and stability.

[0028] The cross bar 4 is connected between two first support rods 1 to enhance the stability of the structure of the new retractable A-frame pole. Preferably, the cross bar 4 is made of steel material, and its length and position can be adjusted according to the opening degree of the first support rods 1.

[0029] Preferably, to improve the flexibility and convenience of the new retractable A-frame pole, the base 2 is detachably connected to the lower end of the first support rod 1.

[0030] In this embodiment, through the setting of the limit support mechanism 5, the new retractable A-frame pole can provide stable support in the horizontal direction for the facility to be erected during the erection process, which helps to accurately control the position of the facility to be erected and reduce the occurrence of deviation of the facility to be erected during the erection process. The support block 54 can adjust the telescopic length by adjusting the telescopic mechanism 53 according to the needs of different sizes of the facility to be erected and topographic conditions, and abut against the facility to be erected to ensure that the facility to be erected is accurately installed according to the pre-planned position, thus ensuring the safety and accuracy of the erection operation. The setting of the limit support mechanism 5 in this solution simplifies the configuration of the erection tools. The second support rod 51 and the first support rod 1 are both connected in a hinged manner, so that the new retractable A-frame pole as a whole can be retracted and unfolded in a "person" shape, and its portability and flexibility are effectively improved.

[0031] Figure 3 The cross-sectional structure diagram of a new retractable A-frame pole in the embodiment of the present application is shown. As Figure 3 shown, in order to meet the erection requirements of different sizes of facilities to be erected, both first support rods 1 adopt a telescopic structure and fix the telescopic position through a locking mechanism to ensure the stability of the first support rods 1. In one implementation, the first support rod 1 includes an outer support rod 11, an inner support rod 12 sleeved on the outer support rod 11, a lining kit 13 arranged at the connection of the outer support rod 11 and the inner support rod 12, and a second pin 14 passing through and connecting the outer support rod 11, the inner support rod 12 and the lining kit 13.

[0032] Figure 2 The cross-sectional structure diagram of a limit support mechanism in the embodiment of the present application is shown. As Figure 2 shown, in one implementation, the telescopic mechanism 53 includes: a screw 531 and an adjustment knob 532. The fixed block 52 is provided with a threaded through hole, and the screw 531 is threadedly connected to the fixed block 52.

[0033] Specifically, a threaded through-hole is provided at the center of the fixed block 52, and the screw rod 531 is connected to the fixed block 52 through threading, enabling the screw rod 531 to move axially along the center of the fixed block 52. One end of the screw rod 531 passing through the fixed block 52 is connected to the support block 54, and the other end is fixed by the adjustment knob 532. The adjustment knob 532 is used to adjust the protruding length of the screw rod 531, thereby adjusting the position of the support block 54. In this embodiment, by providing the telescopic structure 53, the position of the support block 54 can be adjusted according to the specific dimensions and weight of the facility to be assembled before the assembly operation starts, ensuring that it can provide sufficient supporting force, improving the safety, accuracy and efficiency of the assembly operation, and at the same time reducing the operation difficulty and cost.

[0034] Continue to refer to Figure 1 , on the basis of the previous embodiment, in order to ensure the stability of the fixed block 52, in one implementation, the limiting and supporting mechanism 5 further includes: a telescopic support mechanism 56 installed at the bottom of the fixed block 52.

[0035] Specifically, the telescopic support structure 56 can be a telescopic rod that expands and contracts in the vertical direction to adapt to different terrains and operation requirements, providing additional supporting force for the limiting and supporting mechanism 5, and also increasing the stress points of the new retractable gin pole, enabling more stable assembly operations.

[0036] Continue to refer to Figure 1 , in one implementation, the limiting and supporting mechanism 5 further includes: a snap ring 55 connected to the rear end of the second support rod 51, and the limiting and supporting mechanism 5 is clamped to the lower part of the first support rod 1 through the snap ring 55.

[0037] In this embodiment, by connecting the limiting and supporting mechanism 5 and the first support rod 1 through the snap ring 55, not only can the accidental detachment of the limiting and supporting mechanism 5 during use be avoided, ensuring its stability when bearing external forces, but also the limiting and supporting mechanism 5 can be quickly installed and disassembled, improving the efficiency of on-site operations. Optionally, the snap ring 55 is made of a metal material with certain elasticity, thereby reducing the difficulty of clamping to the first support rod 1 and being able to withstand a certain amount of tensile force without deformation.

[0038] Continue to refer to Figure 1 , on the basis of the previous embodiment, the second support rod 51 and the snap ring 55 are connected by a hinge. Specifically, this connection method enables the distance between the two second support rods 51 to be adaptively adjusted as the distance between the two first support rods 1 increases when the first support rod 1 adjusts the opening and closing angle, giving it a larger range of movement, and can also ensure that the position of the support block 54 remains basically unchanged or only has a small offset, so that it is not necessary to disassemble the limiting and supporting mechanism 5 for adjustment, effectively improving the flexibility of the gin pole during the assembly operation and the efficiency of the assembly operation.

[0039] Continue to refer to Figure 3 In one implementation, the base 2 includes a hinge seat 21 and a hinge arm 22 mounted on the hinge seat 21. The hinge arm 22 is sleeved inside the first support rod 1 and is connected to the hinge arm 22 and the first support rod 1 through a first pin 6 in a penetrating manner.

[0040] Specifically, in order to ensure the stability and flexible rotation at the connection between the base 2 and the first support rod 1, the outer diameter of the hinge arm 22 should be slightly smaller than the inner diameter of the first support rod 1, the diameter of the hinge seat 21 should be larger than the inner diameter of the first support rod 1, and through holes are provided at corresponding positions of the hinge arm 22 and the first support rod 1, so that the first pin 6 can pass through the through holes, penetrate through the hinge arm 22 and the first support rod 1, and then lock the first pin 6 to achieve a tight connection between the two.

[0041] In this embodiment, by providing a base 2 with a hinge structure, the first support rod 1 is allowed to freely rotate in at least one direction, so that the angle and position of the new retractable gin pole can be adjusted according to actual needs, adapting to more types of erection operation tasks, effectively improving the flexibility of the new retractable gin pole. The sleeved connection method effectively improves the portability and flexibility of the new retractable gin pole.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
