Description

Technical Field

[0001] The utility model relates to the technical field of pole tower assembly construction, in particular to a temporary pole tower pulling wire device. Background Art

[0002] Temporary guy wires are measures taken during the construction of pole towers to ensure construction safety and improve construction efficiency. The function of temporary guy wires is to support the pole towers to ensure that they will not fall over or other dangerous situations will occur during construction.

[0003] Common temporary tensioning methods for pole towers include burying ground anchor plates and setting ground anchor piles on the ground. The burying of ground anchor plates requires excavating ground anchor pits and horse paths. The size of the horse paths is limited and there is an angle between them and the ground, which makes them difficult to shape and easily causes horse paths to collapse. In addition, the excavation of ground anchor pits and horse paths is time-consuming and labor-intensive, and the efficiency is low. When temporary tensioning is set by burying ground anchor piles on the ground, the position of the ground anchor piles is fixed by friction after the ground anchor piles are hammered into the ground. Since the ground anchor piles are long and have small external dimensions, the friction between the ground anchor piles and the ground is limited, making it difficult to provide a large pulling force for the pole tower to stabilize the pole tower.

[0018] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0019] In one embodiment, see Figure 1 The utility model discloses a temporary wire pulling device for a pole tower, comprising an anchor pile 1 and an anchor support assembly.

[0020] Among them, a connecting ring 2 is provided on the anchor pile 1, and an anchor line 3 is connected to the anchor ring; the anchor support assembly includes a support arm rod 4 arranged on the anchor pile 1, an adjusting member 5 movably arranged on the supporting wall rod, and a support plate 6 movably arranged at the bottom end of the adjusting member 5; the support arm rod 4 is perpendicular to the anchor pile; the adjusting member 5 is inclined relative to the support arm rod 4 to form an angle α, and the extension line of the adjusting member 5 intersects with the anchor pile 1, so that a triangle is formed between the adjusting member 5, the anchor pile 1, and the support arm rod 4.

[0021] Furthermore, the angle α between the support arm 4 and the adjustment member 5 is controlled between 30° and 60°.

[0022] Preferably, the angle α between the support arm 4 and the adjusting member 5 is 45°.

[0023] In the above arrangement, when the anchor pile 1 is driven into the ground, the angle β between the anchor pile 1 and the ground is controlled to be consistent with the angle α when entering the ground, so that after the anchor pile 1 is driven into the ground, the extension line direction of the support arm 4 is away from the ground, and after the adjustment member 5 and the support plate 6 are installed, the adjustment member 5 is perpendicular to the ground.

[0024] Furthermore, a connecting screw sleeve 7 is provided at one end of the support arm 4 away from the ground anchor rod; the adjusting member 5 includes an adjusting screw rod, and the adjusting screw rod is installed in the adjusting screw sleeve through a thread.

[0025] Preferably, a screw hole 8 is provided on the connecting screw sleeve 7, one end of the adjusting screw passes through the screw hole 8 and is threadedly connected to the screw hole 8, and the end of the connecting screw passing through the screw hole 8 is a smooth rod 9.

[0026] Furthermore, an abutment sleeve 10 is provided on the support plate 6 , and one end of the adjusting screw passes through the connecting screw sleeve 7 and is located in the abutment sleeve 10 .

[0027] Preferably, the abutting sleeve 10 is a hollow cylinder with one end open, and the abutting sleeve 10 is welded to the supporting plate 6 .

[0028] Furthermore, the inner diameter of the abutment sleeve 10 is larger than the outer diameter of the adjusting screw, and the distance from the abutment sleeve 10 to the end of the support plate 6 close to the anchor pile is smaller than the distance from the abutment sleeve 10 to the end of the support plate 6 away from the anchor pile.

[0029] Preferably, the abutment sleeve 10 is arranged at one end of the support plate 6 close to the anchor pile.

[0030] In the above arrangement, after the anchor pile is hammered into the ground, the inclination angle of the anchor pile relative to the ground may have an error and be difficult to be consistent with the angle α. By setting the inner diameter of the abutment sleeve 10 to be larger than the outer diameter of the adjusting screw, after the anchor pile is hammered into the ground, the end of the adjusting screw passing through the connecting screw sleeve 7 can still be located in the abutment sleeve 10, thereby abutting the adjusting screw with the abutment sleeve 10 and the support plate 6. In the process of the anchor pile being subjected to force, the anchor pile is overturned by the force of the tension anchor line 3, and the force is transmitted to the adjusting screw through the support arm 4, and finally acts on the support plate 6. If the anchor pile is displaced, it is necessary to overcome the anchor The friction between the pile and the soil and the downward pressure of the anchor pile, the support arm 4, the adjusting screw and the support plate 6 on the ground (when the force transmitted from the anchor pile along the support arm 4 acts on the adjusting screw, it can be decomposed into a horizontal thrust and a vertical downward pressure. Since the support arm 4 flips with the anchor pile, the downward pressure is greater than the thrust). At this time, if the anchor pile flips, the force is transmitted to the adjusting screw and the support plate 6, thereby pressing down the support plate 6. By adding the support arm 4, the adjusting member 5 and the support plate 6, the force required for the anchor pile to move is increased, thereby enhancing the stability of the anchor pile.

[0031] Furthermore, the support plate 6 includes a plate sleeve 11 and a telescopic plate 12 slidably disposed in the plate sleeve 11 , wherein the telescopic plate 12 is located at both sides of the plate sleeve 11 ; and the abutting sleeve 10 is disposed on the plate sleeve 11 .

[0032] Preferably, the plate sleeve 11 is a hollow rectangular body with a hollow interior and openings at both ends, and the telescopic plate 12 is slidably located in the openings at both ends of the plate sleeve 11 .

[0033] In the above arrangement, the telescopic plate 12 can be pulled out from both ends of the plate sleeve 11, thereby increasing the length of the support plate 6. The abutment sleeve 10 is located in the length direction of the support plate 6 and adjacent to one side of the anchor pile 1. The length of the support plate 6 is lengthened by the telescopic plate 12, thereby increasing the contact area between the support plate 6 and the ground. The abutment sleeve 10 is arranged in the length direction of the support plate 6. When the support plate 6 is subjected to a downward force, the force is transmitted to the plate sleeve 11 and the telescopic plate 12. Since the support plate 6 abuts against the ground, a reaction force is applied to the anchor pile 1, thereby stabilizing the position of the anchor pile 1.

[0034] The support plate 6 is then placed on the ground, the ground being leveled and firm in advance, the adjusting screw is turned and the support plate 6 is moved, so that the end of the adjusting screw is inserted into the abutment sleeve 10. After the end of the adjusting screw enters the abutment sleeve 10, the adjusting screw can be turned again and moved toward the ground, thereby applying prestress to the support plate 6. Under the reaction force, the force is transmitted to the anchor pile 1, thereby providing stable support for the anchor pile 1. When the anchor line 3 applies tension to the anchor pile 1, the force can be directly transmitted to the support plate 6, thereby ensuring the stability of the anchor pile 1 and providing a stable anchor foundation for the temporary tension line of the pole tower.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
