However, if the model of the hand wheel is small, the use efficiency of the lever is low, the transmitted torque is small, and if the hand wheel is operated by multiple persons, the labor cost is further increased, but the space is possibly limited; if the handwheel is of a larger size, the torque transmitted is improved, but unnecessary cost waste is caused, and the requirement on operation space is higher.
A fixed U/L-shaped handle designed abroad has no relative movement because the handle and the brake screw rod are fixed in a welding connection mode. The fixed design is not easy to manually loosen the drum braking device by a single person under the braking working condition with larger braking force, the labor cost can be increased by using a plurality of persons, and the inconvenience is also caused to the work. Meanwhile, the disassembly and assembly are complicated, and the repair and replacement of parts are not facilitated.
Disclosure of Invention
An object of the utility model is to provide a lever brake operating means to solve the problem among the prior art.

The utility model has the advantages that:
1. the hand wheel type braking device designed in China also adopts the supporting and lubricating rotation functions of a sliding bearing to rotate a hand wheel, but if the type of the hand wheel is small, the use efficiency of a lever is low, the transmitted torque is small generally, and the labor cost is improved by double operation; if the handwheel model is large, the transmitted torque is improved, but the cost is wasted unnecessarily. The operating device reduces the material cost, increases the use of the lever principle and enlarges the lever efficiency;
2. compared with a fixed U/L-shaped handle designed abroad, the handle and the brake screw are free from the constraint of fixing in a welding connection mode, and the instantaneous pushing force generated by relative motion is increased. The design is more flexible, so that the operation of manually releasing the brake device by a single person is easier to realize under the braking working condition with larger braking force;
in a word, this set of operating means under the prerequisite that does not influence the functional effect, more ingenious application lever principle has enlarged the instantaneous driving force that the handle produced to the guide bar for labour saving and time saving has more practiced thrift the cost in the during operation. The bolt is adopted for fixing, and the disassembly and the assembly during the repair or the replacement of parts are very simple, convenient and quick.

Detailed Description
The technical scheme of the invention is further explained in detail with the accompanying drawings as follows:
example (b): as shown in figure 1, a rod-type brake operating means, including handle assembly 6, lead power pole assembly 5 and brake screw 8, 6 middle parts of handle assembly are provided with handle assembly through-hole, handle assembly through-hole one side is L type handle, lead power pole assembly 5 including lead power pole through-hole and lead the power pole, it crosses with handle assembly through-hole opposite side handle orthographic projection face to lead the power pole, handle assembly through-hole and lead the power pole through-hole and cup joint with brake screw 8, lead power pole assembly 5 and be connected with brake screw through interior hexagonal shaft hole, it is connected with brake screw through the bolt to lead power pole through-hole one side.
Install slide bearing 7 in the handle assembly through-hole, slide bearing 7 is 2mm with 8 axial separation distances of brake screw, and slide bearing 7 makes the handle rotate more nimble on brake screw 8.
And an oil nozzle, a baffle and an indicating plate are further arranged on one side of the force guide rod through hole, the oil nozzle, the baffle and the indicating plate are connected with a brake screw rod 8 through bolts, the oil nozzle, the baffle and the indicating plate are fixed in a unified mode, and the axial positioning from the baffle to a sliding bearing 7 is realized.
As shown in fig. 2, an axial screw hole is formed in the brake screw 8, a vertical screw hole is formed in the position, corresponding to the sliding bearing 7, of the brake screw 8, the axial screw hole is communicated with the vertical screw hole, the oil nipple is connected to the axial screw hole, lubricating oil can be added through the oil nipple, and it is guaranteed that the handle rotates more smoothly on the brake screw 8.
The utility model discloses a theory of operation is:
when the brake operating device is integrally installed, the handle assembly 6 and the sliding bearing 7 are installed in place on the brake screw 8, and the sliding bearing plays a dual role in supporting, lubricating and rotating. And then according to actual stress conditions in different directions of two working states of brake release and brake, the force guide rod assembly 5 is arranged on the brake screw rod 8 in a hexagonal connection mode. After different directions of two working states of brake release and brake are determined, the indicating plate and the baffle plate are fastened on the brake screw rod in a threaded connection mode of bolts. And finally, installing the oil nozzle, adding a proper amount of lubricating oil while rotating the handle assembly 6, ensuring sufficient lubrication and covering the oil nozzle cap. Therefore, the whole device realizes positioning and meets the use requirement after installation.
When the brake device works, the handle assembly 6 is operated by hand, the inertia of relative motion generated by the handle assembly 6 and the brake screw 8 is utilized to impact the brake screw to generate instantaneous driving force, so that the brake device with large braking force can be conveniently loosened, and the labor cost is reduced. When the handle assembly 6 rotates, one end of the handle assembly drives the force guide rod assembly 5 to complete circular motion together with the force guide rod assembly. When one end of the L-shaped handle is selected to drive the force guide rod assembly 5, the lever principle effect is not obvious; when the other end is selected to drive the force guide rod assembly 5, the lever principle effect is obvious. Therefore, the brake screw 8 synchronously rotates to transmit torque under two different working conditions of loosening and braking, and the working requirement of a user on the brake is met.
