Description

Technical Field

[0001] The utility model relates to a road paving fixing device, belonging to the field of road paving equipment. Background Art

[0002] During the road pipeline laying process, a clamp device for fixing the pipeline needs to be installed at the lifting end of the crane, so that the pipeline to be laid can be lifted and laid in a ditch pre-opened on the road.

[0003] In the prior art, pipe clamps used for road paving all clamp the pipes by closing a fan-shaped opening. However, during the expansion of the fixed clamp, the opening expands in a fan-shaped manner, causing the opening to be larger than the size of the ditch and unable to move into the ditch for pipe laying, thus causing the pipe that falls into the ditch to roll.

[0004] In summary, the utility model therefore provides a road paving fixing device to solve the above-mentioned problems. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model aims to provide a road paving fixture to solve the problem in the above background technology that the internal clamps of the fixture occupy a large space when unfolded and cannot be moved to the inside of the road ditch for pipe laying and material cutting.

[0006] In order to achieve the above-mentioned purpose, the utility model is implemented through the following technical scheme: a road paving fixing device, including a connecting seat, fastening screws are penetrated all around the bottom of the connecting seat, electric lifting rods are fixedly connected all around the bottom of the connecting seat, a fixing seat is fixedly connected between the output ends of the four electric lifting rods, an electric slide rail is embedded in the bottom of the fixing seat, the electric slide rail is semi-circular, a slide groove is opened on the inner arc surface of the electric slide rail, and electric sliders are slidably connected to both sides of the slide groove of the electric slide rail, and a circumferential clamping seat is fixedly connected to the bottom of the two electric sliders.

[0007] Furthermore, the two circumferential clamping seats are both shaped in a circular arc shape, and the curvature of the two circumferential clamping seats is the same as the curvature of the electric slide rail.

[0008] Furthermore, the fixing seat is fixedly connected to the electric slide rail, and the two circumferential clamping seats are installed in a mirror-symmetrical structure.

[0009] Furthermore, the front side of the fixing seat is flush with the front side of the electric slide rail, and the back side of the fixing seat is flush with the back side of the electric slide rail.

[0010] Furthermore, the circumferential clamp seat includes a clamp plate, which is in the shape of an arc-shaped curved plate. The clamp plate is fixedly connected to the bottom of the electric slider. The inner arc surface of the clamp plate is provided with a mounting groove. A plurality of mounting shafts are connected between the two sides of the inner wall of the mounting groove so as to rotate evenly around the center of the inner arc surface of the clamp plate. The axial surface of each mounting shaft is sleeved with a transmission roller sleeve.

[0011] Furthermore, the installation shaft is fixedly connected to the transmission roller sleeve, and the bottom end of the clamping plate is beveled.

[0012] Furthermore, the inner arc surfaces of the clamping plates inside the two circumferential clamping seats are spliced ​​to form a semicircular clamping groove, and the roller surface of the transmission roller sleeve extends to the outside of the installation groove.

[0013] Beneficial effects of the utility model:

[0014] By starting the two electric slide rails, driving the two electric sliders to slide in opposite circles and driving the two clamps to reset, the bottom notch of the semicircular clamping groove formed by the two clamps can be opened, so that the opening between the two clamps will not expand in a fan-shaped shape, and the diameter is smaller than the diameter of the road pipeline laying ditch, which effectively reduces the ditch area occupied by the road laying fixture in the process of clamping the pipeline and laying it, so that the entire device can penetrate deep into the road ditch, and the pipeline can be accurately placed at a fixed position inside the ditch, reducing the phenomenon of pipeline rolling caused by falling into the pipeline from a high altitude.

[0015] When two clamps are used to clamp the pipes used for road paving, the inner arc side of the clamp will contact the pipes. The rotating transmission roller sleeve can reduce the friction force in the process of adjusting the clamps to clamp the pipes, reduce the resistance generated by the internal motor drive components when doing work, and extend the service life of the device.

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] See also Figure 1-4 The utility model provides a technical solution: a road paving fixing device, including a connecting seat 1, fastening screws 2 are penetrated around the bottom of the connecting seat 1, and the connecting seat 1 is fixedly connected to the cable end of the external hoist through four fastening screws 2. The connecting seat 1 is fixedly connected to the electric lifting rod 3 around the bottom of the connecting seat 1. The four electric lifting rods 3 are connected to the external power supply and are provided with the same power control switch. A fixing seat 4 is fixedly connected between the output ends of the four electric lifting rods 3. An electric slide rail 5 is embedded at the bottom of the fixing seat 4. The electric slide rail 5 is semi-circular. A slide groove is opened on the inner arc surface of the electric slide rail 5, and electric sliders 6 are slidably connected to both sides of the slide groove of the electric slide rail 5. The bottoms of the two electric sliders 6 are fixedly connected to a circumferential clamping seat 7. The electric slide rail 5 is a device for moving equipment or objects. It drives the internal slider to move by an electric motor so that it can move smoothly and accurately. The electric slider 6 is a kind of electric motor driven, which can realize The present invention provides a device for linear or other complex trajectory motion, which is used in combination with an electric slide rail 5. The electric slide rail 5 is electrically connected to the two electric sliders 6 through a wire, and the sliding directions of the two electric sliders 6 are opposite. The shaping shapes of the two circumferential clamping seats 7 are both arc-shaped, and the curvature of the two circumferential clamping seats 7 is the same as the curvature of the electric slide rail 5. The fixed seat 4 is fixedly connected to the electric slide rail 5, and the two circumferential clamping seats 7 are installed in a mirror-symmetrical structure. The front side of the fixed seat 4 is flush with the front side of the electric slide rail 5, and the back side of the fixed seat 4 is flush with the back side of the electric slide rail 5. When the electric slide rail 5 is started, the two electric sliders 6 can be driven to slide in opposite directions on the arc-shaped slide groove of the electric slide rail 5, thereby driving the two circumferential clamping seats 7 to slide in a circle around the center of the curvature of the electric slide rail 5, so that the road-laid pipes can be clamped and fixed, and the external hoist is started to drive the device as a whole to rise and fall, so that the pipes can be fixed and laid.

[0024] See also Figure 2-4The circumferential clamping seat 7 includes a clamping plate 71, which is in the shape of an arc-shaped curved plate. The clamping plate 71 is fixedly connected to the bottom of the electric slider 6. The inner arc surface of the clamping plate 71 is provided with a mounting groove 72. A plurality of mounting shafts 73 are connected between the two sides of the inner wall of the mounting groove 72 so as to rotate evenly around the center of the inner arc surface of the clamping plate 71. The axial surface of each mounting shaft 73 is sleeved with a transmission roller sleeve 74, and the transmission roller sleeve 74 can be rotated by the mounting shaft 73. When the clamping plates 71 inside the two circumferential clamping seats 7 slide in opposite directions at the same time, a semicircular clamping groove is formed, and the pipeline to be laid is clamped and fixed in the process of forming the semicircular clamping groove. During the clamping process, the inner arc side surface of the clamping plate 71 will contact the pipeline, and the friction force of the clamping plate 71 in the process of clamping the pipeline can be reduced by rotating the transmission roller sleeve 74.

[0025] See also Figure 2-4 The mounting shaft 73 is fixedly connected to the transmission roller sleeve 74. The bottom end of the clamping plate 71 is beveled. The bottom ends of the two clamping plates 71 can quickly scoop up the pipe placed on the road surface and clamp it. After the two clamping plates 71 are unfolded, the opening size between the bottoms is smaller than the diameter of the pipe. The inner arc surfaces of the clamping plates 71 inside the two circumferential clamping seats 7 are spliced ​​to form a semicircular clamping groove. The roller surface of the transmission roller sleeve 74 extends to the outside of the mounting groove 72. The two clamping plates 71 can slide circumferentially inside the electric slide rail 5 through the electric slider 6. When the two clamping plates 71 pass through the two When the electric slider 6 performs reverse circular sliding inside the electric slide rail 5 and resets, the bottom notch of the semicircular clamping groove formed by the two clamping plates 71 can be opened without making the opening between the two clamping plates 71 too large, so that after the pipeline is clamped by the device as a whole, the device as a whole can be placed in a pipeline laying ditch opened on the road, so that the pipeline is closest to the bottom of the inner wall of the ditch. During the road pipeline laying process, the pipeline can be accurately placed at a fixed point inside the ditch, reducing the phenomenon of pipeline rolling caused by falling into the pipeline from a high altitude.

[0026] Specific implementation method: The entire device is moved by a crane, and the semicircular clamping groove formed between the inner clamping plates 71 of the two circular clamping seats 7 is moved and sleeved above the pipe placed on the road surface, so that the inner arc surface of the clamping plate 71 contacts the surface of the pipe, and then the electric slide rail 5 is started to drive the two electric sliders 6 to move, and the two electric sliders 6 can be driven to slide in opposite directions on the arc-shaped slide groove of the electric slide rail 5, thereby driving the two circular clamping seats 7 to slide in a circle around the center of the curved arc of the electric slide rail 5, so that the pipe laid on the road can be clamped and fixed, and the external crane is started to drive the entire device to rise and fall, so that the pipe can be fixed and laid.

[0027] When the two clamping plates 71 slide in opposite circles inside the electric slide rail 5 through the two electric sliders 6 and reset, the bottom notch of the semicircular clamping groove formed by the two clamping plates 71 can be opened, so that the opening between the two clamping plates 71 will not be fan-shaped and the diameter is smaller than the diameter of the road pipeline laying ditch. Therefore, after the pipeline is clamped by the device as a whole, the device as a whole can be placed in the pipeline laying ditch opened on the road, so that the pipeline is closest to the bottom of the inner wall of the ditch. During the road pipeline laying process, the pipeline can be accurately placed at a fixed position inside the ditch to reduce the phenomenon of pipeline rolling caused by falling into the pipeline from a high altitude.

[0028] In the process of clamping the pipes used for road paving by two clamping plates 71, the inner arc side of the clamping plate 71 will contact the pipe. The rotating transmission roller sleeve 74 can reduce the friction force of the clamping plate 71 in the process of adjusting the clamping pipe, reduce the resistance generated by the internal motor drive component when doing work, and extend the service life of the device.

[0029] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
