Description

Technical Field

[0001] The utility model relates to the technical field of power pipe processing, in particular to a MMP pipe processing clamping device. Background Art

[0002] MPP power pipe is also called MPP power cable protection pipe and MPP cable protection pipe. It is divided into trenchless type and non-excavation type. MPP non-excavation power pipe is also called MPP jacking pipe or dragging pipe. MPP power pipe uses modified polypropylene as the main raw material. It is a construction project that does not require a large amount of mud, excavation and damage to the road surface. It can be used to lay pipelines and cables in special areas such as roads, railways, buildings, and riverbeds.

[0003] For example, the patent publication number CN202222739598.9 discloses a centering clamping device for MMP power pipe processing, which sets a positioning mechanism. The first cylinder drives the connecting rod to drive the hinged rods on both sides to move the mounting rod inward, so that the clamping plate follows the diameter of the pipe fitting to ensure the fixation of the center position of the pipe fitting and prevent the pipe fitting from deformation during processing; by setting a clamping mechanism, the second cylinder drives the inner gear plate to move downward to rotate the transmission gear, driving the U-shaped plate to move upward synchronously, so that the displacement of the upper clamping block and the lower clamping block is equal, so that the center height of the pipe fitting is consistent when clamping, but this technical solution still has shortcomings, as follows:

[0004] The clamping mechanism can only process MMP tubes of fixed size. When processing different MMP tubes, it is easy to get stuck on the top of the tube body or there is a large gap between the tube body and the clamping mechanism. The use is very limited. In addition, the clamping position is fixed. When clamping tubes of different lengths, the two sides are easy to warp, which is inconvenient to use. To this end, we propose an MMP tube processing clamping device to solve the above-mentioned problems. Utility Model Content

[0041] The following is combined with Figure 1-5The utility model is described in further detail.

[0042] Embodiment 1, refer to Figure 1-3 In order to solve the existing problem that the clamping cannot be freely selected according to the length of the pipe body, the utility model discloses a MMP pipe processing clamping device.

[0043] include,

[0044] The device assembly 100 further includes a device body 101, and a side plate 102 is connected to the upper side of the device body 101;

[0045] The adjustment component 200 also includes a linkage block 201, which is located above the device body 101. Extension plates 202 are connected to both sides of the linkage block 201. The extension plates 202 cooperate with the linkage block 201 to limit the linkage block 201. Insertion blocks 204 are connected to both sides of the extension plate 202. A connecting rod 203 is connected to the top of the insertion block 204. The insertion block 204 can be quickly lifted up by the connecting rod 203, thereby facilitating the adjustment of the position of the insertion block 204. An insertion slot 2011 is connected to the bottom of the insertion block 204.

[0046] Side panels 102 are symmetrically distributed on both sides above the device body 101, and insertion grooves 2011 are evenly and equidistantly distributed above the device body 101. The insertion grooves 2011 and the insertion blocks 204 engage with each other. The position of the linkage block 201 is changed by the cooperation between the insertion blocks 204 and the insertion grooves 2011, thereby changing the position of the clamping assembly 300.

[0047] Extension plates 202 are hot-melt connected on both sides of the linkage block 201. The extension plate 202 is connected to the insertion block 204 by sliding connection. The insertion block 204 and the connecting rod 203 are installed in an integrated manner. The insertion block 204 can be quickly lifted by the connecting rod 203 to adjust the position of the linkage block 201, which is convenient for staff to operate.

[0048] The specific working principle is: first, the tube body to be processed is passed through the first limit plate 306 and then clamped by the clamping block 304 for processing. If the tube body is too long or too short, it cannot be clamped in the appropriate position. Before clamping, pull the connecting rod 203 to drive the insertion block 204 to rise and disengage from the insertion groove 2011, thereby releasing the limit fixation of the linkage block 201, and then move the linkage block 201 until the tube body can be clamped in the appropriate position. Press the connecting rod 203 to drive the insertion block 204 to insert into the insertion groove 2011, complete the fixation of the linkage block 201, and then use the clamping block 304 to clamp it.

[0049] Example 2, refer to Figure 1-3In this embodiment, in order to solve the problem that the existing clamping mechanism cannot limit and fix different pipe bodies, based on the same concept as the above-mentioned embodiment 1, the MMP pipe processing clamping device also includes:

[0050] The clamping assembly 300 also includes a driving motor 301, which is located inside the linkage block 201. A driving screw 302 is connected to the top of the driving motor 301. The driving screw 302 rotates in both directions to make the clamping blocks 304 move toward each other or away from each other to ensure that the clamping work is carried out. A clamping block 304 is connected to the top of the driving screw 302. A limiting rod 307 is connected to the outer side of the clamping block 304. The clamping block 304 is fixed by the limiting rod 307 to prevent it from shaking. The clamping block 304 is located inside the protective shell 305. A first limiting plate 306 is also connected to the top and outer side of the linkage block 201. The first limiting plate 306 assists in limiting the tube body to prevent it from shaking.

[0051] The driving motor 301 and the driving screw 302 are connected by a key connection. The thread directions of the upper and lower sides of the driving screw 302 are opposite. The driving screw 302 rotates integrally with the driving screw 302 on the other side through the connecting belt 303. The driving screw 302 with opposite thread directions allows the clamping blocks 304 to move towards or away from each other, ensuring rapid clamping.

[0052] The driving screw 302 and the clamping block 304 are connected by a threaded connection, a rotating structure is provided between the clamping blocks 304, and the clamping block 304 and the limiting rod 307 are connected by a sliding connection. Through the rotating structure between multiple clamping blocks 304 and the clamping blocks 304, the clamping blocks 304 can be deformed so as to fit on the surface of the tube body, thereby ensuring the clamping of tubes of any size.

[0053] The first limiting plate 306 is connected to the linkage block 201 by hot-melt connection. A circular groove is provided at the center of the first limiting plate 306. The center of the first limiting plate 306 and the center of the clamping block 304 are above the same horizontal line. The first limiting plate 306 is used to limit the tube body for the second time to prevent the tube body from tilting, and the auxiliary clamping block 304 is used to fix it.

[0054] The specific working principle is as follows: as described above, during the clamping process, the tube body is passed through the first limit plate 306 for preliminary limit, and then the tube body enters between the clamping blocks 304, and the switch of the driving motor 301 is turned on, so that the driving motor 301 drives the driving screw 302 above it to rotate, and then the driving screw 302 and the clamping block 304 undergo threaded motion, and under the limit of the limit rod 307, the clamping blocks 304 move towards each other, and at the same time, the driving screw 302 drives the driving screw 302 on the other side to rotate through the connecting belt 303, and the clamping block 304 on the other side also moves towards each other, and the clamping blocks 304 on both sides gradually fit together during the movement to complete the limit fixation of the tube body. At the same time, because there is a rotating structure between the clamping blocks 304, the central clamping block 304 will rotate with the clamping blocks 304 on both sides until it is completely fitted to the tube body to complete the fixing work.

[0055] Example 3, refer to Figure 4-5 In order to solve the problem that the clamping block 304 is easily shaken during the processing of the existing pipe body, the present embodiment, based on the same concept as the above-mentioned embodiment 1, the MMP pipe processing clamping device further includes:

[0056] The auxiliary component 400 also includes a second limit plate 401, which is located above the linkage block 201. The second limit plate 401 is internally connected to a rotating rod 403, and the auxiliary plate 402 is fixed by the rotating rod 403, so that the auxiliary plate 402 can rotate freely and adapt to a tube body of any size. The other side of the rotating rod 403 is connected to the auxiliary plate 402, and the auxiliary plate 402 is connected to a shock-absorbing spring 404 above the auxiliary plate 402. The shock-absorbing spring 404 is internally connected to a shock absorber 405. The shock-absorbing spring 404 cooperates with the shock absorber 405 to complete the fixed limit, which is convenient for shock absorption and prevents the tube body from falling off due to vibration.

[0057] The second limiting plate 401 forms a rotating structure with the auxiliary plate 402 through the rotating rod 403. The auxiliary plates 402 are evenly and equidistantly distributed around the center of the second limiting plate 401. The auxiliary plate 402 has a semi-arc structure. The second limiting plate 401 cooperates with the auxiliary plate 402, so that the auxiliary plate 402 can be adjusted according to the size of the tube body to ensure the fixing of the tube body.

[0058] The auxiliary plate 402 forms a spring shock-absorbing structure with the second limit plate 401 through the shock-absorbing spring 404. The shock-absorbing spring 404 and the shock absorber 405 are connected in parallel. The shock-absorbing spring 404 and the second limit plate 401 are installed as an integral whole. Through the cooperation between the shock-absorbing spring 404 and the shock absorber 405, the auxiliary plate 402 can dampen the tube body, further stabilize the tube body, and prevent the clamping block 304 from falling off.

[0059] The specific working principle is: as mentioned above, when the tube body enters the interior of the second limit plate 401, the auxiliary plate 402 is first squeezed so that the auxiliary plate 402 rotates through the rotating rod 403, thereby fitting to the tube body, and at the same time the shock-absorbing spring 404 drives the auxiliary plate 402 to reset and fit to the surface of the tube body. When the tube body vibrates during processing, the shock absorber 405 cooperates with the shock-absorbing spring 404 to buffer and protect the tube body to prevent its vibration from causing unstable clamping of the clamping block 304.

[0060] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
