Description
Technical Field
The invention relates to the technical field of cableway safety test, in particular to a cable clamping device anti-skid force test device.
Background
The reciprocating cableway is a passenger cableway, and is a cableway scheme which is preferably selected under the conditions of complex terrain, large height difference and large span due to the characteristics of large climbing capacity, large span, high spacious ground height, high running speed, strong wind resistance and the like.
The working principle of the reciprocating cableway is as follows: each side of the cableway line is provided with one or a group of buses, the buses run on the carrying rope through travelling wheels arranged on the buses, the traction rope is fixed with the buses, and the driving machine drives the traction rope to make the buses reciprocate on the line. The traction cable and the passenger car are connected by a friction reel, a casting sleeve and a cable clamping device, and the cable clamping device has the advantages of convenient installation, simple displacement, reliability, durability, good maintainability and the like, and is widely applied to the reciprocating cableway. Most of the cable clamping devices used in the current cableway construction engineering are similar in structure and principle, and only the applicable traction cables are different in diameter.
Because the different topography conditions of each project, the inclination angle of the cableway steel wire rope is different, when the inclination angle of the steel wire rope on a line is larger, the self gravity of a suspended carriage and passengers can cause the cable clamping device to generate larger sliding force relative to a traction cable, and if the sliding occurs, serious consequences of vehicle destruction and human death are easily caused. Therefore, it is important to be able to accurately test the anti-slip force of the grip.
At present, no special device for testing the anti-skid force of the rope clamping device of the reciprocating cableway exists, and the existing anti-skid force measurement of the rope clamping device mainly adopts a field measurement mode. The measurement is performed on site using a wire rope 22', a chain block 23', and a tension meter 24', as in the general on-site measurement method shown in fig. 1. The measurement method has the following defects:
1) Because the test steel wire rope 22 'has a certain vertical distance from the traction rope 1' when the traction rope is loaded with tension, extra moment influence can be generated on the rope clamping device 2', even the situation that the steel wire rope 22' is not parallel to the traction rope 1 'sometimes exists, and errors can be caused between test data and the actual anti-skid capability of the rope clamping device 2';
2) The steel wire rope 22 'for testing can directly act on the upper end of the rope clamping device 2' or the connecting plate 21 'of the bus 25', so that moment influence can be generated for some cableways needing larger anti-skid force, and certain damage can be caused to equipment;
3) The anti-skid force test scheme of the rope clamping device is a field test scheme, the chain block 23' needs to find a proper fixed stress point, can be limited by field conditions, and has lower test efficiency.
4) The anti-skid force of the rope clamping device 2' can be tested only after the rope clamping device 2', the traction rope 1', the hanging box and the like are installed in place, and if equipment has a problem, the on-site treatment is difficult.
In view of the above-mentioned problems in the existing measuring methods of the anti-slip force of the rope clamping device, a safer and more efficient testing scheme of the anti-slip force of the rope clamping device is needed.

The specific meaning of the above terms in the present invention will be understood in specific cases by those of ordinary skill in the art.
Fig. 2 and 3 are front and top views, respectively, of a grip anti-skid force test device according to an embodiment of the present invention.
As shown in fig. 2 and 3, the anti-skid force testing device for the rope clamp provided by the invention comprises a base 3, a saddle 33 vertically arranged on the base 3 and a traction rope 1, wherein the front end of the traction rope 1 is connected with the middle part of a front plate 32 of the base 3 through a first tension adjusting mechanism 5 after being guided by the cambered surface of the saddle 33, and the rear end of the traction rope 1 is connected with a rear plate 31 of the base 3 through a first rope clamping plate 311; the rope clamping device 2 to be tested is arranged on the main body part of the traction rope 1 between the rear plate 31 and the saddle 33, the rope clamping device 2 to be tested is connected with a tensioning rope 41, the tensioning rope 41 is parallel to the main body part of the traction rope 1, one end of the tensioning rope 41, which is far away from the rope clamping device 2 to be tested, is connected with a tension meter 4, and one end of the tension meter 4, which is far away from the tensioning rope 41, is connected with the upper part of the front plate 32 through a second tension adjusting mechanism 42.
In the actual test, since the portion of the traction cable 1 located at the front side of the saddle 33 is connected to the middle portion of the front plate 32 of the base 3 through the first tension adjusting mechanism 5 after being guided by the arc surface of the saddle 33, interference with the tightening rope 41 of the traction cable 1 can be avoided. In addition, after the end of the traction rope 1 is tensioned through the first tension adjusting mechanism 5, the main body part of the traction rope 1 is tensioned along the horizontal direction, so that the test precision of the rope clamping device 2 to be tested on the main body part of the traction rope 1 can be ensured. Furthermore, flanges 34 may be disposed on both front and rear sides of the cambered surface of the saddle 33, and the traction cable 1 is located between the two flanges 34, so as to prevent the traction cable 1 from moving along the direction perpendicular to the traction cable 1.
It should be noted that, because the traction cable 1 has a certain ductility, in the process of gradually stressing, the tension of the traction cable 1 at the right end of the cable clamping device 2 to be tested can be obviously reduced, which is different from the actual working condition of the traction cable 1, and may cause inaccurate anti-skid force test data of the cable clamping device 2 to be tested, so that the traction cable 1 needs to be tensioned by the first tension adjusting mechanism 5 to improve the test precision.
In addition, an anchor cylinder 312 is arranged above the rear plate 31, and the rear end of the traction rope 1 is connected with the rear plate 31 through a first rope clamping plate 311 after being wound by the anchor cylinder 312; at least two positioning stoppers 313 are provided on the anchor cylinder 312, and a portion of the traction cable 1 wound around the anchor cylinder 312 is limited between two adjacent positioning stoppers 313. In the actual operation process, the rear end of the traction rope 1 is wound for a plurality of circles (at least one circle) by the anchoring barrel 312 at the left side of the rope clamping device anti-skid force testing device and then is fixed by the first rope clamping plate 311, and the anchoring barrel 312 effectively disperses the tensile force of the rear end of the traction rope 1, so that the stress of the rope end of the traction rope 1 can be obviously reduced. In addition, the positioning stop block 313 is arranged on the anchoring cylinder 312, so that the traction rope 1 can be prevented from axially moving along the anchoring cylinder 312 when being stressed, and the traction rope 1 can be kept stable when being stressed during testing.
Further, fig. 4 shows the structure of the first tension adjusting mechanism 5 according to the embodiment of the present invention, and as can be seen from fig. 4, the first tension adjusting mechanism 5 includes a second rope clamping plate 52, a first bolt 54 fixed on the front plate 32, and a first adjusting nut 53 provided on the first bolt 54 (the first bolt 54 and the first adjusting nut 53 are generally provided with two sets to promote the stability of the first tension adjusting mechanism 5); the front end of the traction rope 1 is clamped and fixed with a second rope clamping plate 52, an adjusting plate 51 is fixed on the second rope clamping plate 52, a first perforation is formed in the adjusting plate 51, and one end of a first bolt 54, which is far away from the front plate 32, penetrates through the adjusting plate 51 through the first perforation; the adjustment plate 51 is adjusted in position by a first adjustment nut 53 on a first bolt 54.
Since the front end of the traction cable 1 is fixed by the second rope clamping plate 52, the nut end of the first bolt 54 is fixed to the front plate 32 of the device base 3, and the first adjusting nut 53 on the first bolt 54 is screwed to move axially along the first bolt 54, so that the adjusting plate 51 is pushed to gradually tighten or gradually loosen (depending on the screwing direction) the traction cable 1 fixed by the second rope clamping plate 52. The first tension adjusting mechanism 5 is configured such that the axial direction of the first bolt 54 is on the same plane as and parallel to the traction cable 1, thereby ensuring stable tensioning of the traction cable 1 in one direction.
In the actual installation process, the upper end of the cable clamping device 2 to be tested and the traction cable 1 are screwed and fixed through bolts, and the bolts are required to be screwed to a screwing moment design value meeting the design requirement of the anti-skid force of the cable clamping device. The lower end of the cable clamping device is fixed by bolts through a connecting plate 22 and a thrust seat 21. Fig. 5 shows a front view of the thrust bearing 21 according to the embodiment of the present invention; fig. 6 shows a right-hand structure of a thrust seat 21 according to an embodiment of the present invention, as can be seen from fig. 3, 5 and 6, the thrust seat 21 is connected to the rear end of the cable clamping device 2 to be tested through a connecting plate 22, and two first pull rings 23 are symmetrically arranged on the thrust seat 21 in an inner-outer direction; the tension rope 41 is arranged in a middle folded manner, the folded ends of the tension rope 41 are connected with the tension meter 4 through the second pull rings 73, and the double-end ends of the tension rope 41 are respectively connected with the two first pull rings 23.
It should be noted that, the connecting plate 22 with the same thickness and material as the bus connecting plate 22 and designed in the middle of the thrust seat 21 is the same as the actual working condition of the cable clamping device 2 to be tested and is used for being connected with the cable clamping device 2 to be tested through bolts. The first pull rings 23 which are designed on two sides and can bear large pulling force are respectively fixed with the double-end ends of the tensioning rope 41, so that the tensioning rope 41 is prevented from being in direct forced contact with the cable clamping device 2 or the connecting plate 22 to be tested, and equipment is prevented from being damaged.
Specifically, the second tension adjusting mechanism 42 includes a second bolt and a second adjusting nut (not specifically shown in the drawings), and a second through hole is opened in the upper portion of the front plate 32; one end of the second bolt is connected with one end of the tension meter 4 away from the tensioning rope 41, and the other end of the second bolt penetrates through the front plate 32 through the second through hole and then is in threaded connection with the second adjusting nut.
The test tension of the whole device is mainly generated by rotating and tightening the second bolt and the second adjusting nut, and the stress application mode is simple and reliable. When the force is applied, the second bolt drives the related connecting piece (mainly comprising the tension meter 4) to horizontally move rightwards along the F direction shown in fig. 2, the moving direction and the tensioning direction of the traction rope 1 are in the same straight line, and no additional moment is generated on the rope clamping device 2 to be tested.
In addition, in order to facilitate the traction cable 1 to pass through the thrust seat 21, a through groove 24 may be formed in the thrust seat 21, and the main body portion of the traction cable 1 passes through the thrust seat 21 through the through groove 24.
The invention uses the digital display type tension meter 4, which is externally connected with display equipment, can display the loaded tension value in real time, prevents overload and is convenient for data recording.
In addition, fig. 7 shows a top view of the rope guide 7 according to an embodiment of the present invention, fig. 8 shows a structure of the arc-shaped intermediate plate 71 according to an embodiment of the present invention, and fig. 9 shows a structure of the arc-shaped clamping plate 72 according to an embodiment of the present invention. As can be seen from fig. 7 to 9, the double-folded end of the tightening rope 41 is sleeved with a rope guide plate 7, a connecting hole is formed in the rope guide plate 7, and the tension meter 4 is connected with the rope guide plate 7 through a second pull ring 73 matched with the connecting hole.
Specifically, the rope guide 7 may include two arc-shaped clamping plates 72 and an arc-shaped intermediate plate 71, wherein the arc-shaped intermediate plate 71 is sandwiched between the two arc-shaped clamping plates 72; and, the area of the two arc clamping plates 72 is larger than that of the arc middle plate 71, so that an arc groove is formed between the two arc clamping plates 72 and the arc middle plate 71; the folded end of the tensioning rope 41 is sleeved in the arc-shaped groove.
It should be noted that the two arc clamping plates 72 and the arc middle plate 71 are both fan-shaped or semicircular in design. The design can reduce the bending of the tensioning rope 41 when being stressed, ensure that the tensioning rope 41 gives the same tension to the two ends of the thrust seat 21, and ensure that the thrust seat 21 cannot deviate; on the other hand, both ends of the tension rope 41 provided in two halves are led to both sides of the center in the pulling force direction by the rope guide plate 7, so that the tension rope 41 can be effectively prevented from interfering with the saddle 33 and the traction rope. In addition, since the areas of the two arc clamping plates 72 are larger than the area of the arc middle plate 71, the folded ends of the tensioning rope 41 can be sleeved in the arc grooves, and the up-and-down movement of the tensioning rope 41 can be effectively blocked.
Specifically, to form the connection hole, an outward slot 721 is formed in the two arc clamping plates 72, an inward slot 711 is formed in the arc middle plate 71, and the connection hole is formed after the two outward slots 721 are vertically aligned with the inward slot 711.
It should be noted that, unlike the prior art solutions, all the generated forces are converted into internal forces between the devices during the testing process, and no force points are present outside. In the actual manufacturing process, the base 3 is made of high-strength alloy steel, a cross brace (not shown in the figure) is arranged between the device base 3 and the saddle 33, stability of the saddle 33 is guaranteed, triangular diagonal braces (not shown in the figure) are adopted on two sides, and the device base 3 can bear a larger counter force of test tension. The clearance between the flange 34 of the saddle 33 and the two positioning stops 313 is kept at 26mm, and the traction rope is suitable for traction ropes 1 with most diameters of reciprocating cableways. Therefore, the device is suitable for the anti-skid force test of the cable clamping device with various models.

4. All the generated forces of the anti-skid force testing device for the rope clamping device are converted into internal forces between the devices, and the external force points are not needed, so that the anti-skid force testing device is not limited by external conditions.
The grip anti-skid force test device according to the present invention is described above by way of example with reference to fig. 1 to 9.
