Description

Technical Field

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

[0002] The rubber-drawing tube is a concrete core mold made of natural rubber. It is mainly used for prestressed ducts in bridges, precast box girders in high-speed railways, and pre-reserved holes in building construction. When using it, the steel strand is first inserted into the inner hole of the rubber-drawing tube to prevent it from being squeezed and deformed when pouring concrete. Then the rubber-drawing tube is inserted into the prestressed hole position, and then the concrete is poured. After the concrete has initially set, it can be pulled out. Traditional tube-drawing machines pull out the rubber-drawing tube and then use a winch to drag the rubber-drawing tube for recovery. However, since the winch has no traveling device and needs to be moved mechanically, and when dragging the rubber hose, it is necessary to bury pre-embedded parts in the ground to fix the winch, its operation efficiency is low, the operation intensity is high, and it is time-consuming and labor-intensive. Utility Model Content

[0003] The purpose of this utility model is to provide a traction device to address the problems in the background technology where the winch has no traveling device and needs to be mechanically transferred, and the winch needs to be fixed by pre-embedded parts buried in the ground when dragging and pulling the rubber hose, which results in low operation efficiency, high operation intensity, and time and labor costs.

[0024] The present invention will be further described in detail below with reference to specific embodiments. However, it should not be construed as limiting the scope of the present invention to the following embodiments; all technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0025] Unless otherwise specified, the use of terms such as "upper," "lower," "left," "right," "center," "inner," and "outer" to indicate orientation or positional relationships in the description of specific embodiments of this utility model is based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product / equipment / device is typically placed during use. These terms are merely for the purpose of facilitating the description of the utility model solution or simplifying the description in specific embodiments, enabling those skilled in the art to quickly understand the solution, and do not indicate or imply that a specific device / component / element must have a specific orientation, or be constructed and operated in a specific positional relationship. Therefore, they should not be construed as limitations on this utility model.

[0026] Furthermore, the use of terms such as "horizontal," "vertical," "suspended," "parallel," and "coaxial" does not imply that the corresponding device / component / element must be absolutely horizontal, vertical, suspended, parallel, or coaxial. Slight tilt or deviation is permissible, as long as it does not affect the normal function of the relevant component. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," not that the structure must be perfectly horizontal; a slight tilt is acceptable. "Coaxial" means that two components are set as coaxially as possible, allowing them to move coaxially or approximately coaxially when their relative positions change. Alternatively, it can be simplified to mean that the corresponding device / component / element, when set in a "horizontal," "vertical," "suspended," "parallel," or "coaxial" direction, can have an error / deviation of ±10% relative to the corresponding direction, more preferably within ±8%, more preferably within ±6%, more preferably within ±5%, and more preferably within ±4%. For example, the deviation in the "coaxial" direction is controlled within 0.2-1mm, preferably within 0.2-0.5mm. As long as the corresponding device / component / element is within the error / deviation range, it can still achieve its function in the present invention.

[0027] Furthermore, the use of terms such as "first," "second," and "third" in terminology is merely for distinguishing descriptions of identical or similar components and should not be interpreted as emphasizing or implying the relative importance of a particular component.

[0028] Furthermore, in the description of the embodiments of this utility model, "several", "multiple", and "several" represent at least two. The number can be any number, such as two, three, four, five, six, seven, eight, or nine, and can even exceed nine.

[0029] Furthermore, in the description of the technical solution of this utility model, unless otherwise explicitly specified / limited / restricted, the terms "set up," "install," "connect," "link," "equipped with," "laid out," and "arranged" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to common connection methods in the art, such as welding, riveting, bolting, and threaded connections. Such connections can be mechanical, electrical, or communication connections; they can be direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components.

[0030] Example 1 like Figures 1-7 As shown, a traction device includes: A cart 1, on which a winch 10 is installed; Multiple auxiliary toolings, including a sleeve rod 2 and a diagonal rod 3, with the two ends of the sleeve rod 2 being a first snap-fit ​​end 21 and a second snap-fit ​​end 22, and the diagonal rod 3 connected to the sleeve rod 2; The auxiliary tooling is configured such that when the first card connector 21 is detachably connected to the trolley 1, the diagonal bar 3 tilts upward; When the second locking end 22 is detachably connected to the trolley 1, the diagonal bar 3 tilts downward and abuts against the ground.

[0031] In this embodiment, the winch 10 is mounted on the trolley 1 to facilitate its relocation for dragging and pulling the hose at different locations. Furthermore, the auxiliary tooling includes a sleeve rod 2 and a diagonal rod 3. The sleeve rod 2 has a first locking end 21 and a second locking end 22 at both ends. The diagonal rod 3 is connected to the sleeve rod 2. When the trolley 1 needs to be pushed, the first locking end 21 of the sleeve rod 2 is detachably connected to the trolley 1. At this time, the diagonal rod 3 tilts upwards, acting as a push handle. The operator pushes the trolley 1 using the diagonal rod 3. This allows the trolley 1 to move. When it is necessary to drag the rubber tube, the second snap-fit ​​end 22 of the sleeve 2 is detachably connected to the trolley 1. At this time, the diagonal rod 3 tilts downward and abuts against the ground. The diagonal rod 3 is equivalent to a tilting support leg. The trolley 1 is supported and fixed by multiple diagonal rods 3 abutting against the ground, so that the trolley 1 is fixed on the ground, which facilitates the winch 10 to drag the rubber tube. The traction device of this embodiment is simple to operate and easy to use. It can be moved and fixed in place, which greatly improves the rubber tube recovery operation.

[0032] In optional implementations, such as Figure 1 , Figure 2 As shown, the upper edge of the trolley 1 is provided with multiple uprights 4; like Figure 3 , Figure 4 , Figure 5 As shown, when the first snap-fit ​​end 21 is downward and sleeved on the upright 4, the diagonal bar 3 is inclined upward; like Figure 3 , Figure 6 , Figure 7 As shown, when the second snap-fit ​​end 22 is downward and sleeved on the upright 4, the diagonal rod 3 tilts downward and abuts against the ground.

[0033] By setting a vertical pole 4 on the trolley 1, it is easy to sleeve the rod 2 on the vertical pole 4 to form a detachable connection. When the first snap-fit ​​end 21 is downward and sleeved on the vertical pole 4, the inclined rod 3 is inclined upward. At this time, the inclined rod 3 is equivalent to a push handle and is used to push the trolley 1. When the second locking end 22 is downward and sleeved on the upright 4, the diagonal rod 3 tilts downward and abuts against the ground. At this time, the diagonal rod 3 is equivalent to a tilting support leg, used to fix the trolley 1.

[0034] Furthermore, such as Figure 2 As shown, each of the four corners of the trolley 1 is equipped with a vertical pole 4 and an auxiliary tool.

[0035] By setting up a vertical pole 4 and an auxiliary tool at each of the four corners of the trolley 1, the trolley 1 can be better secured.

[0036] In an optional embodiment, both the upright 4 and the sleeve 2 are rectangular tubes.

[0037] The rectangular tube has a rectangular cross-section, and its adjacent side walls are perpendicular. After the upright 4 is inserted into the sleeve 2, the corner constraints of the rectangular cross-section prevent the two from rotating relative to each other in the circumference. The inner wall of the sleeve 2 and the outer wall of the upright 4 form a surface contact. The mutual restraint between the side walls directly blocks the rotational freedom of the sleeve 2 and the upright 4, so that a certain side wall of the upright 4 is always aligned with the corresponding side wall of the sleeve 2, thereby accurately positioning the installation position of the diagonal rod 3 and ensuring that the support direction of the diagonal rod 3 is fixed. In an optional implementation, when fixing the trolley 1, such as Figure 6 , Figure 7 As shown, two diagonal rods 3 located at the front of the trolley 1 support the front of the trolley 1, and two diagonal rods 3 located at the rear of the trolley 1 support the rear of the trolley 1. The winch 10 is installed in the rear area of ​​the trolley 1.

[0038] In an optional implementation, when fixing the trolley 1, such as Figure 8 , Figure 9 As shown, two diagonal rods 3 located at the front of the trolley 1 support the front of the trolley 1, and two diagonal rods 3 located at the rear of the trolley 1 support the left and right sides of the trolley 1. The winch 10 is installed in the rear area of ​​the trolley 1.

[0039] In an optional embodiment, the length of the upright 4 is 30cm to 35cm; The length of the second sleeve is 35cm to 40cm.

[0040] In an optional implementation, the auxiliary tooling is a steel component.

[0041] In optional implementations, such as Figure 3 As shown, the sleeve rod 2 and the inclined rod 3 form a V-shaped structure. The first locking end 21 of the sleeve rod 2 is away from the opening of the V-shaped structure, and the second locking end 22 of the sleeve rod 2 is located inside the opening of the V-shaped structure.

[0042] In an optional embodiment, an anti-slip sleeve is provided on the outer side of the end of the diagonal bar 3 away from the sleeve bar 2. When pushing the trolley 1, the operator grips the anti-slip sleeve of the diagonal bar 3 more securely.

[0043] Example 2 Based on Example 1, this embodiment discloses a method for using a traction device, as follows: First, make auxiliary tooling, in which the sleeve rod 2 and the inclined rod 3 form a V-shaped structure. The first locking end 21 of the sleeve rod 2 is away from the opening of the V-shaped structure, and the second locking end 22 of the sleeve rod 2 is located inside the opening of the V-shaped structure.

[0044] When it is necessary to recycle the rubber tube, the first snap-fit ​​end 21 of the sleeve rod 2 is placed downward and sleeved on the upright rod 4, so that the inclined rod 3 is tilted upward. At this time, the inclined rod 3 is equivalent to a push handle, and the operator uses the inclined rod 3 to push the cart 1 to move to the work area. Then, when the second locking end 22 of the sleeve rod 2 is lowered and sleeved on the upright rod 4, the diagonal rod 3 tilts downward and abuts against the ground. At this time, the diagonal rod 3 is equivalent to a tilting support leg, used to fix the trolley 1 on the ground. Then, the wire rope of the winch 10 is connected to the rubber tube, and then the winch 10 is started to drag the rubber tube, dragging the rubber tube out and arranging it neatly for recycling.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
