[0022] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.
[0023] Those skilled in the art will appreciate that, although some embodiments herein include certain features included in other embodiments but not other features, the combination of features of different embodiments is meant to be within the scope of the present invention and form different embodiments. For example, in the claims, any one of the claimed embodiments may be used in any combination.
[0024] Please refer to the attached Figure 1 To Attachment Figure 3 The utility model describes a steel strand pulling device.
[0025] The existing method of dragging the steel strand requires people to hold the steel strand clamp 2 and the universal clamp, and manually operate the universal clamp to break the torsional stress inside the steel strand. However, the manual follow-up operation is not only labor-intensive, but also has safety issues and low efficiency.
[0026] Therefore, if Figure 1 and Figure 2 As shown, the utility model provides a steel strand pulling device, including a base slide plate 1, on which a steel strand clamp 2 is provided, in which a clamping tooth plate 201 is provided, the clamping tooth plate 201 is fixedly connected to the steel strand, and the clamping tooth plate 201 is rotatably connected to the steel strand clamp 2. The base slide plate 1 is used to contact the ground, so as to protect the structure on the base slide plate 1 from being damaged by external friction. The device is fixedly connected to the steel strand through the clamping tooth plate 201. When torsional stress is generated inside the steel strand, the clamping tooth plate 201 rotates relative to the steel strand clamp 2 to break the stress inside the steel strand.
[0027] like Figure 2 As shown, a tooth plate slide groove 202 is provided on the steel strand clamp 2, and the tooth plate slide groove 202 is rotatably connected to the clamping tooth plate 201, so that the clamping tooth plate 201 is rotatably connected to the steel strand clamp 2.
[0028] A bearing protection groove 203 is provided at one end of the steel strand clamp 2 away from the tooth plate slide groove 202, and a bearing 204 is provided in the bearing protection groove 203. The outer ring of the bearing 204 is fixedly connected to the bearing protection groove 203, and the inner ring of the bearing 204 is fixedly connected to the clamping tooth plate 201, so that the relative rotation between the steel strand clamp 2 and the clamping tooth plate 201 is simpler and smoother, thereby improving the stability of the rotation of the clamping tooth plate 201 and further improving the sensitivity of the steel strand clamp 2 to break the stress of the steel strand.
[0029] The tooth plate slot 202 is conical, and the clamping tooth plate 201 includes a fan-shaped tooth plate 2011, which is slidably connected to the tooth plate slot 202. The fan-shaped tooth plate 2011 can be axially contracted or expanded to adapt to the shape of the tooth plate slot 202. When the fan-shaped tooth plate 2011 moves in the first direction A, the fan-shaped tooth plate 2011 contracts axially to gradually reduce the diameter of the inlet end of the fan-shaped tooth plate 2011, thereby locking the steel strand in the fan-shaped tooth plate 2011. It should be noted that the first direction A is the opposite direction in which the steel strand extends into the steel strand clamp 2, and the steel strand extends into the steel strand from the inlet end of the fan-shaped tooth plate 2011.
[0030] As a preferred example, Figure 3 As shown, the sector tooth plate 2011 uses three toothed sector plates to form a cone that matches the toothed plate slot 202, and clamps the steel strand by friction self-locking. It can be understood that the number and shape of the toothed sector plates can be selected according to actual needs.
[0031] A spring pressure plate 2012 is provided on the outer side of the fan-shaped tooth plate 2011, and the spring pressure plate 2012 limits the fan-shaped tooth plate 2011 in the first direction A to prevent the fan-shaped tooth plate 2011 from slipping out of the tooth plate slide groove 202. A tensioning spring 2013 is connected to the spring pressure plate 2012, and the tensioning spring 2013 is located at the end of the spring pressure plate 2012 away from the tooth plate slide groove 202. The end of the tensioning spring 2013 away from the spring pressure plate 2012 is connected to a spring base 2014, and the outer sleeve of the spring base 2014 is connected to a base ring 2015. The spring base 20 14 can slide relative to the base ring 2015, and the base ring 2015 is fixedly connected to the inner ring of the bearing 204. The spring base 2014 slides relative to the base ring 2015 in the first direction A, so that the diameter of the fan-shaped tooth plate 2011 is reduced, so as to achieve the purpose of clamping the steel strand, and the spring pressure plate 2012 is pressed by the tensioning spring 2013 to improve the vibration resistance of the steel strand clamp 2, so as to avoid the phenomenon that the internal fan-shaped tooth plate 2011 and the steel strand are disengaged due to the uneven ground after the rigid clamping of the steel strand.
[0032] Preferably, a male thread is provided on the outer side of the spring base 2014, the outer side of the base ring 2015 is fixedly connected to the inner ring of the bearing 204, and a female thread matching the spring base 2014 is provided on the inner side of the base ring 2015, so that the spring base 2014 is screwed with the base ring 2015. The spring base 2014 is moved relative to the base ring 2015 by rotating the spring base 2014. Specifically, the spring base 2014 is rotated to move in the first direction A to clamp the steel strand, and the relative position of the spring base 2014 and the base ring 2015 can be locked by screwing the spring base 2014 with the base ring 2015.
[0033] Optional, such as Figure 4 As shown, in order to facilitate the locking and fixing of the steel strand, the spring base 2014 is a circular ring structure, and the inner ring diameter of the spring base 2014 is larger than the diameter of the steel strand to facilitate the passage of the steel strand. A groove 100 is provided on the spring base 2014, and the staff uses a tool to abut against the groove 100 to rotate the spring base 2014.
[0034] like Figure 1 As shown, a wire rope clamp 3 is also provided on the base slide plate 1 , and the wire rope clamp 3 is connected to the winch wire rope. The winch wire rope passes through the wire rope clamp 3 to provide driving force for the base slide plate 1 .
[0035] The wire rope clamp 3 comprises a first clamping plate 301 and a second clamping plate 302 . The first clamping plate 301 is fixedly connected to the base slide plate 1 , and the second clamping plate 302 is detachably connected to the first clamping plate 301 .
[0036] Optional, such as Figure 1 As shown, the base slide plate 1 is fixedly connected to the steel strand clamp 2 , and the steel strand clamp 2 is fixedly connected to the first clamping plate 301 .
[0037] Preferably, the first clamping plate 301 and the second clamping plate 302 are detachable high-carbon alloy steel fan-shaped pressure plates, which contain anti-stripping teeth. The first clamping plate 301 and the second clamping plate 302 are connected by a semi-open one-way push-pull separable conical structure, and the second clamping plate 302 can be separated from the first clamping plate 301 by pushing the second clamping plate 302 in one direction. The conical structure further improves the structural strength, tensile strength and yield of the first clamping plate 301 and the second clamping plate 302, and improves the tension that the wire rope clamp 3 can withstand. When the wire rope is inserted into the first clamping plate 301 and the second clamping plate 302, the greater the driving force generated by the winch wire rope, the greater the clamping force of the first clamping plate 301 and the second clamping plate 302 on the winch wire rope.
[0038] Optionally, in order to facilitate the installation of the wire rope by the wire rope clamp 3, a handle for easy disassembly and installation may be provided on the second clamping plate 302.
[0039] The base slide 1 is fixedly connected with a rocker plate 4, which is arranged at an angle with the base slide 1, so that the base slide 1 has good wear resistance and protection, prevents obstruction by foreign objects, and plays a role in smooth operation when the device moves. As a preferred embodiment, Figure 2 As shown, the angle α between the rocker plate 4 and the base slide plate 1 is 150 degrees.
[0040] The rocker plate 4 is provided with a hoist wire rope through hole 402 which is matched with the wire rope clamp 3 so that the rocker plate 4 and the hoist wire rope do not interfere with each other.
[0041] Preferably, a lifting ring 205 is provided on the top of the steel strand clamp 2 for easy lifting. The strength of the lifting ring 205 meets the requirements for lifting the overall structure, and the device is easy to lift when encountering steps or other places with height differences.
[0042] Preferably, a lifting hole 401 is provided on the base slide plate 1 for easy lifting, so that the device can be easily lifted when encountering a position where the horizontal surface is difficult to pass.
