Description

The invention relates to the construction of clamping cable devices, in particular to cable suspended roads.

A clamping device is known (patent RU (11) 2010738, class B61B 12/12, 1994), comprising a housing with two supporting elements and a spring-loaded clamping grip for fixing the clamped cable, mounted between the supporting elements on the housing with the possibility of movement relative to the latter.

The disadvantage of this design of the clamping device is the mechanical disconnection of the clamp from the rope, which leads to large dynamic loads on the clamping device. This leads to a decrease in the speed of the rolling stock.

The closest (taken as a prototype) in terms of design features, technical nature and the achieved result to this invention is an automatic rope clamping device (patent FR 2697056, class B61B 12/12, 2000), containing a housing, in the rear of which on the sides two rollers are installed to move along the rails and at the top on the sides there are two rigidly fixed racks on one side, and on the other side at the bottom of the rack with a threaded fastener holding the lower fixed cover, in which the lower part rifles and a freely moving push rod, which is rigidly connected in the upper part to another freely moving cover, into which the upper part of the spring is inserted. The front part of the body, made by a fixed lower jaw, in its upper part parallel to the axis of the rope, is pivotally connected to the upper movable jaw-lever and, in turn, the end of the lever is connected to the upper movable lid, on which, in turn, the control roller is mounted, with the possibility of moving the jaw lever around the axis of the swivel. The release of the upper sponge-lever occurs due to the collision of the control roller on an external device, while the spring is compressed and the rope is released.

This design has the following disadvantages:

- large mass and overall dimensions,

- large inertial mass characteristics,

- the resulting dynamic load on the clamp when disconnecting the clamping device from the rope while driving the control roller on the external device.

The objective of the invention is

- reduction of dynamic loads by reducing the size and weight,

due to the monolithic structure of the hull, dimensions and weight can be reduced;

- reduction of inertial mass characteristics,

due to the reduction in size and mass, the inertial-mass characteristics are reduced;

- reducing the dynamic load on the clamp when disconnecting the clamping device,

due to the smooth attraction of the external magnetic control device of the movement of the element of the magnetic bar.

The objective of the invention is solved due to the fact that the automatic cable clamping magnetic device, consisting of a forked casing with racks fixed to it with a lower fixed and upper movable cover, has a lower part of the spring and a push rod connected in the lower part to the control element and in the upper part - by a threaded connection with the upper movable cover, in which the upper part of the spring is installed, on one side the forked housing is equipped with rollers, and on the other hand it is made in the form of a movable jaw connected by a hinge to a movable jaw-lever connected by a hinge to the upper movable cover, and a suspension rod is installed at the bottom of the housing, the forked housing has a monolithic structure with racks made in the form of a plate bent shape and rigidly fixed to the bottom a fixed cover, the working part of the pushing rod is square in shape and is rigidly fixed to a control element made in the form of a magnetic bar, under which an external magnetic control is located an impressive device.

Technical result:

to reduce the weight and dimensions, as well as the inertial-mass characteristics, it is possible due to the fact that the forked body has a monolithic structure with racks made in the form of a plate bent shape and rigidly fixed to the lower fixed cover,

- to reduce the dynamic load on the clamp when the magnetic strip is attracted to an external control device, it is possible due to the fact that the working part of the pushing rod is square in shape and is rigidly fixed to the control element made in the form of a magnetic strip,

- to reduce the dynamic load on the clamp can be due to the fact that an external magnetic control device attracts the magnetic bar.

Figure 2 presents the automatic cable clamping magnetic device in a different projection.

The automatic cable clamping magnetic device consists of a forked housing 1 with struts 2 fixed on it with a lower fixed 3 and an upper movable 4 covers, a lower part of a spring 5 and a push rod 6 connected in the lower part to a control element 7 are installed in the lower fixed cover 3 and in the upper part - a threaded connection 8 with the upper movable cover 4, in which the upper part of the spring 5 is installed, on one side the forked housing 1 is equipped with rollers 9, and on the other is made in the form of a fixed jaw 10 connected to using the hinge of the hinge 11 with a movable sponge-lever 12 connected via a hinge 13 to the upper movable cover 4, and also from the bottom of the housing 1, a suspension rod 14 is installed, and the forked housing 1 has a monolithic structure with racks 2 made in the form of a plate bent shape and rigidly fixed on the lower fixed cover 3, the working part of the pushing rod 6 is made square in shape and is rigidly fixed to a control element made in the form of a magnetic strip 7, under which there is an external magnetic control device 15.

The automatic cable clamping magnetic device operates as follows. At the loading and unloading stations of the suspended passenger ropeway at each station, two external control devices 15 are installed at the entrance and exit of the rolling stock for disconnecting from the rope and connecting to the rope an automatic cable clamp magnetic device. The rope is unloaded due to the attraction of the control element of the magnetic strip 7 by an external magnetic control device 15, while the spring 5 is compressed, the rod 6 goes down with the upper movable cover 4 and the sponge lever 12, the hinge joints 11, 12 rotate and the rope is released. The rope is clamped in the same manner.
