Description

Technical Field

[0001] This utility model relates to the fields of engineering technology such as municipal engineering, water conservancy and hydropower, and water transport, and in particular to a steel pipe dismantling device. Background Technology

[0002] In engineering construction safety protection, it is often necessary to temporarily insert steel pipes into the ground and install relevant warning signs to form steel pipe piles. This type of protection is characterized by its flexible layout and ease of relocation. After use, the steel pipes need to be pulled out. However, due to some ground geological conditions or improper installation, the steel pipes are difficult to pull out by hand, thus requiring tools.

[0003] Existing tools, such as the device for pulling out underground fixed poles disclosed in patent publication number CN218437040U, employ a lever and a V-shaped plate fixed to the lever. In use, one end of the lever is placed on the ground, the V-shaped plate engages with the steel pipe, and then the lever is raised, pulling the steel pipe out through the V-shaped plate. However, this method has a limited lever travel, and in hard ground, insufficient travel can cause the steel pipe to jam, making it difficult to pull out. Utility Model Content

[0004] The purpose of this invention is to provide a steel pipe removal device that provides sufficient lever power stroke to pull out the steel pipe in a more labor-saving manner.

[0005] The technical solution of this utility model is: a steel pipe removal device, including a lever, a locking device hinged to one end of the lever by a first pin, and a support device hinged to the lever by a second pin. The first pin and the second pin form a distance L1, and the second pin forms a distance L2 to the other end of the lever, where L1 < L2. The locking device is provided with a locking cavity for engaging the steel pipe.

[0006] In the above scheme, the locking device for clamping the steel pipe is placed at the end of the lever, a support device is added to the lever, and a structure with L1 < L2 is designed so that the lever can lift (pull out) the steel pipe by pressing down. This structural design gives the lever sufficient power stroke, making it easier and less strenuous to pull out the steel pipe, and is not affected by geological conditions.

[0007] Preferably, the locking device includes a locking block and a first connecting plate connected to the locking block, wherein the end of the first connecting plate away from the locking block is hinged to a lever, and the locking block is provided with the locking cavity.

[0008] Preferably, the locking block includes a first rod and a second rod, two first rods are arranged at two intervals, one end of the two first rods is connected to the second rod, the other end of the two first rods forms an opening, the first rods and the second rods enclose to form the locking cavity, and the first connecting plate is connected to one of the first rods.

[0009] Preferably, two first connecting plates are provided on the lock block, and the two first connecting plates are sandwiched between the two sides of the lever.

[0010] Preferably, the support device includes a base, a support column vertically connected to the base, and a second connecting plate connected to the upper end of the support column, wherein the second connecting plate is hinged to the lever.

[0011] Preferably, both the base and the support column are made of square steel; the base extends along an axis perpendicular to the lever.

[0012] Preferably, two second connecting plates are provided on the support column, and the two second connecting plates are sandwiched between the two sides of the lever.

[0013] Compared with related technologies, the beneficial effects of this utility model are as follows: I. This utility model places the locking device for snapping the steel pipe at the end of the lever, adds a support device to the lever, and designs a structure where L1 < L2, so that the lever can lift (pull out) the steel pipe by pressing down. This structural design gives the lever sufficient power stroke, making it easier and less strenuous to pull out the steel pipe, and is not affected by geological conditions. Second, this utility model is lightweight and easy to carry, and it is also applicable to places where it is difficult to use equipment, such as high slopes and deep foundation pits.

[0016] The present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of the present invention can be combined with each other. For ease of description, the terms "upper," "lower," "left," and "right" appearing below only indicate that they correspond to the upper, lower, left, and right directions in the accompanying drawings and do not limit the structure.

[0017] like Figure 1As shown, the steel pipe removal device provided in this embodiment includes a locking device 1, a supporting device 2, and a lever 3. The locking device 1 is hinged to one end of the lever 3 via a first pin 4, and the supporting device 2 is hinged to the lever 3 via a second pin 5. The first pin 4 and the second pin 5 form a distance L1, and the second pin 5 forms a distance L2 to the other end of the lever 3, where L1 < L2.

[0018] The locking device 1 includes a locking block 11, a locking cavity 12, and a first connecting plate 13. The locking block 11 includes a first rod 111 and a second rod 112. Two first rods 111 are spaced apart, with one end of each first rod 111 connected to the second rod 112, and the other ends of the two first rods 111 forming an opening. The first rods 111 and the second rods 112 together form the locking cavity 12. The first connecting plate 13 is connected to one of the first rods 111. Furthermore, two first connecting plates 13 are provided on the locking block 11, sandwiched between the two sides of the lever 3 (a gap is provided between the first connecting plate 13 and the lever 3 to avoid affecting the movement of the lever 3). The ends of the two first connecting plates 13 away from the first rod 111 are connected to a first pin 4.

[0019] The support device 2 includes a base 21, a support column 22 vertically connected to the base 21, and a second connecting plate 23 connected to the upper end of the support column 22. Two second connecting plates 23 are provided on the support column 22, and the two second connecting plates 23 are sandwiched between the two sides of the lever 3 (a gap is provided between the second connecting plate 23 and the lever 3 to avoid affecting the movement of the lever 3). The end of the second connecting plate 23 away from the support column 22 is connected to the second pin 5. Both the base 21 and the support column 22 are made of square steel; the base 21 extends along an axis perpendicular to the lever 3.

[0020] like Figure 2 As shown, steel pipes 6 are temporarily driven into the ground 7 at the construction site, and warning signs or protective railings are installed on top of the steel pipes 6. As the project progresses, the location of the temporary protection on site is often adjusted, at which point the steel pipes 6 need to be removed.

[0021] When using the steel pipe removal device of this utility model, place the support device 2 on the ground 7 and fit the locking block 11 onto the steel pipe 6, so that the steel pipe 6 is placed in the locking cavity 12. After the position is determined, press the lever 3 downward continuously. Under the action of the support device 2, the locking device 1 moves upward, and the two first rods 111 engage with the steel pipe 6, thereby driving the steel pipe 6 to move upward until it is pulled out of the ground 7.
