Description

Technical Field

[0001] The utility model relates to the technical field of cable suspension devices, in particular to a cable suspension device for a ductile iron pipe extraction vehicle. Background Art

[0002] After centrifugal casting of ductile iron pipes, an extraction vehicle needs to move away from the centrifuge to safely and smoothly remove the ductile iron pipes from the mold, and then proceed to the next process. During the movement of the extraction vehicle, the cable used to supply power to the extraction vehicle also moves back and forth with the extraction vehicle. To avoid cable entanglement and wear, generally, a crossbeam made of I-beam is arranged on the horizontal side beside the movement track of the extraction vehicle, and a plurality of sliding blocks are installed on the crossbeam. A bracket is arranged at the bottom of the sliding block, and the cable is suspended on the bracket. The sliding block drives the cable to reciprocate with the extraction vehicle, thereby avoiding cable entanglement and wear.

[0003] During the working process, the sliding block moves back and forth on the I-beam, moving back and forth thousands of times on average every day. Excessive movements often cause the sliding block to fall off. The fallen sliding block needs to be repaired and then reassembled onto the I-beam, which takes a lot of time. The cables between adjacent sliding blocks are also frequently bent due to extrusion, resulting in easy damage to the cables and the need for replacement. These problems will not only cause production interruption and affect the production progress, but also increase the production cost. Summary of the Utility Model

[0004] The utility model provides a cable suspension device for a ductile iron pipe extraction vehicle to solve the technical problems in the prior art that when using a sliding block to walk on a crossbeam to drag the cable to move, the sliding block is prone to falling off and the cable is prone to bending and damage after long-term use, thereby affecting the production progress and increasing the production cost.

[0005] To solve the above problems, a cable suspension device for a ductile iron pipe extraction vehicle provided by the utility model adopts the following technical solutions:

[0006] A cable suspension device for a ductile iron pipe extraction vehicle includes a support frame body, a rotating shaft, a supporting member and a column. The support frame body includes a vertical beam and a crossbeam. The vertical beam is used to be arranged on the horizontal side beside the movement track of the extraction vehicle. The crossbeam is vertically connected to the top end of the vertical beam, and one end of the crossbeam is connected to the vertical beam, and the other end is used to extend towards the extraction vehicle. The rotating shaft extends in the up and down direction and is rotatably installed on the crossbeam, and the up and down position of the rotating shaft on the crossbeam is fixed. The supporting member is connected to the bottom end of the rotating shaft, and the supporting member is used to support the part of the cable close to the power supply. The column is used to be installed on the extraction vehicle, and a limiting ring is connected to the top end of the column. The limiting ring is used for the cable to pass through, and the column is used to support the part of the cable close to the extraction vehicle.

[0007] Further, the supporting member includes an arc-shaped bent plate section with an opening facing downward and two arc-shaped flat plates respectively connected to both ends in the axial direction of the arc-shaped bent plate. The two arc-shaped flat plates are parallel to each other, and a blocking rod is connected between the two arc-shaped flat plates. There is a gap between the blocking rod and the top surface of the arc-shaped bent plate, and this gap is used for the cable to pass through.

[0008] With the above technical solution, the bent arc-shaped bent plate is used to support the cable. When the cable is placed on the arc-shaped bent plate, it bends naturally, avoiding bending of the cable at the end of the supporting member. A blocking rod is connected between the arc-shaped flat plates, which can limit the cable on the arc-shaped bent plate and prevent the cable from falling off the supporting member.

[0009] Further, a fixing plate is connected to the bottom of the arc-shaped bent plate. The fixing plate is located within the opening area of the arc-shaped bent plate. The bottom end of the rotating shaft passes through the arc-shaped bent plate and fits with the fixing plate. A connecting bolt is inserted through the fixing plate from bottom to top, and the connecting bolt passes through the fixing plate and is screwed into the rotating shaft to connect the rotating shaft to the fixing plate.

[0010] With the above technical solution, the rotating shaft is detachably connected to the fixing plate at the bottom of the arc-shaped bent plate, which is convenient for replacement when the supporting member or the rotating shaft is damaged.

[0011] Further, the cross beam includes a horizontally connected horizontal plate and a vertically connected vertical plate. A through hole penetrating up and down is provided on the horizontal plate. The rotating shaft is arranged in the through hole. Symmetrically arranged fixing sleeves are connected to both the upper and lower sides of the horizontal plate. The fixing sleeves are coaxial with the through hole. Bearings are provided between the two fixing sleeves and the rotating shaft. One of the bearings is in tight fit with the rotating shaft, and the other bearing is in loose fit with the rotating shaft. Both bearings are in loose fit with the fixing sleeves. A fastening screw is screwed onto the fixing sleeve, and the fastening screw passes through the fixing sleeve and presses against the outer side wall of the corresponding bearing.

[0012] With the above technical solution, the bearings are provided to make the rotation of the rotating shaft smoother. The rotating shaft is in tight fit with one of the bearings to fix the rotating shaft in the vertical direction. The rotating shaft is in loose fit with the other bearing, which is convenient for removing this bearing from the rotating shaft. The bearings are in loose fit with the fixing sleeves and are connected by fastening screws. After loosening the fastening screws, first remove the bearing that is in loose fit with the rotating shaft, and then remove the rotating shaft and the bearing that is in tight fit with the rotating shaft, which is convenient for replacing the bearing when the bearing is damaged.

[0013] Further, end caps are provided at the ends of the two fixing sleeves facing away from the horizontal plate. The end caps are connected to the fixing sleeves by fixing bolts.

[0014] With the above technical solution, it can prevent dust from falling into the bearings and extend the service life of the bearings.

[0015] Further, a plurality of limiting rings are arranged at intervals in the vertical direction on the side wall of the column, and the limiting rings are used for the cable to pass through.

[0016] Further, a reinforcing rib plate is provided at the bottom of the column, and the reinforcing rib plate is used to connect between the column and the pipe pulling vehicle.

[0017] The beneficial effects of a cable suspension device for a ductile iron pipe pulling vehicle provided by the utility model are as follows: by providing a support frame body and a column with a certain height to support the cable, the cable is kept in a suspended state and will not come into contact with other structures and collide with other structures during the movement of the pipe pulling vehicle. Compared with the prior art, the cable does not need to move back and forth with the pulley, which can avoid problems such as the pulley falling off and the cable being squeezed and bent, avoid frequent replacement and repair of the pulley or cable, improve the production progress, and reduce the production cost. The rotating shaft can drive the supporting member to rotate. During the movement of the pipe pulling vehicle, the supporting member can rotate following the movement of the cable. Compared with setting a fixed supporting member, the cable will not be bent at the end of the supporting member, avoiding damage to the cable caused by frequent bending at the supporting member.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present invention.

[0026] The following is an embodiment of a cable suspension device for a ductile iron pipe pulling vehicle provided by the present invention:

[0027] As Figure 1 、 Figure 2 shown, a cable suspension device for a ductile iron pipe pulling vehicle includes a support frame body, a rotating shaft 10, a bearing 14, an end cover 11, a support member 9 and a column 7.

[0028] As Figure 1 、 Figure 3 shown, the support frame body includes a vertical beam 3 and a cross beam 4. The vertical beam 3 is used to be arranged on the horizontal side beside the middle position of the moving track 6 of the pipe pulling vehicle 5. The cross beam 4 is vertically connected to the top end of the vertical beam 3, and one end of the cross beam 4 is fixedly connected to the vertical beam 3, and the other end is used to extend towards the pipe pulling vehicle 5. The cross sections of the cross beam 4 and the vertical beam 3 are both L-shaped, and the cross beam 4 and the vertical beam 3 can be specifically made of angle steel. The cross beam 4 includes a horizontally connected horizontal plate 401 and a vertical plate 402. The bottom surface of the horizontal plate 401 is attached to the top surface of the vertical beam 3. A through hole penetrating up and down is provided on the horizontal plate 401, and two symmetrically arranged fixed sleeves 12 are connected to the upper and lower sides of the horizontal plate 401, and the fixed sleeves 12 are coaxial with the through hole.

[0029] The rotating shaft 10 extends in the up and down direction, and the rotating shaft 10 is inserted into the above through hole, and the rotating shaft 10 can rotate in the through hole.

[0030] As Figure 3As shown, there are two bearings 14. The two bearings 14 are coaxially installed in the fixed sleeves 12 respectively, and there is a loose fit between the bearings 14 and the fixed sleeves 12. A fastening screw 17 is screwed onto the fixed sleeve 12. The fastening screw 17 passes through the fixed sleeve 12 and presses against the outer side wall of the corresponding bearing 14 to fix the bearing 14 in the fixed sleeve 12. The above-mentioned rotating shaft 10 is arranged through the two bearings 14. There is a tight fit between the upper bearing 14 and the rotating shaft 10, and a loose fit between the lower bearing 14 and the rotating shaft 10. When the bearing 14 or the rotating shaft 10 is damaged, it is convenient to remove the bearing 14 and the rotating shaft 10 from the horizontal plate 401 for replacement, which can save the replacement time and improve production efficiency.

[0031] There are two end covers 11. The two end covers 11 are respectively connected to one end of the two fixed sleeves 12 facing away from the horizontal plate 401 through fixed bolts 13. The end covers 11 can prevent dust from entering the bearings 14.

[0032] As Figure 3 、 Figure 4 shown, the supporting member 9 includes an arc-shaped bent plate 902 with an opening facing downwards and two arc-shaped flat plates 901 respectively connected to both ends of the arc-shaped bent plate 902 in the axial direction. The two arc-shaped flat plates 901 are parallel to each other. There are two stop bars 19 connected between the two arc-shaped flat plates 901, and the two stop bars 19 are arranged at intervals. There is a gap between the stop bar 19 and the top surface of the arc-shaped bent plate 902, and this gap is used for the cable 2 to pass through. The stop bar 19 is specifically a long bolt. The long bolt passes through the two arc-shaped flat plates 901 and is connected to a nut to be fixed on the two arc-shaped flat plates 901. The long bolt can be removed from the arc-shaped flat plate 901 by loosening the nut.

[0033] As Figure 3 shown, a fixing plate 15 is connected to the bottom of the arc-shaped bent plate 902. The fixing plate 15 is located in the opening area of the arc-shaped bent plate 902. Both ends of the fixing plate 15 are bent, and the fixing plate 15 is welded to the arc-shaped bent plate 902 through the bends. The bottom end of the above-mentioned rotating shaft 10 passes through the arc-shaped bent plate 902 and fits with the fixing plate 15. A connecting bolt 16 is inserted through the fixing plate 15 from bottom to top. The connecting bolt 16 passes through the fixing plate 15 and is screwed into the rotating shaft 10 to connect the rotating shaft 10 and the fixing plate 15.

[0034] As Figure 1 shown, the upright column 7 is used to be installed on the pipe pulling vehicle 5. A limit ring 8 is connected to the top end of the upright column 7. There are two limit rings 8 arranged at intervals up and down on the side wall of the upright column 7 facing away from the support frame.

During the movement of the pipe pulling vehicle 5, the cable 2 is dragged to move back and forth, and the supporting member 9 rotates along with the cable 2 to avoid bending of the cable 2.

[0036] The utility model can effectively avoid the problems of pulley falling off and bending damage of the cable 2. After the bearing 14 fails after long-term use, it is also easy to replace, and the replacement time is short, avoiding affecting the production progress.

[0037] In this embodiment, the rotating shaft 10 is connected to the fixing plate 15 through the connecting bolt 16, so as to realize the detachable connection between the rotating shaft 10 and the supporting member 9. In other embodiments, the rotating shaft 10 is welded to the arc-shaped bent plate 902. At this time, the rotating shaft 10 is fixed on the supporting member 9, and the supporting member 9 and the rotating shaft 10 are not detachable.
