Example 1

The embodiment provides a direction changing device for a handle of a manual reversing valve, and firstly, referring to fig. 1, an overall structure display diagram of the present application is shown, as shown in the diagram, the direction changing device mainly comprises a valve body 1 and a handle 2, the handle 2 is installed on one side of the valve body 1, the specific structures and specific connection relations of the valve body 1 and the handle 2 are the prior art, and are not described herein again, and the model of the manual reversing valve adopted in the present embodiment is 34M-B10H-W; the handle 2 is provided with a linear bearing 3 (the linear bearing 3 is a common existing technology in the market, and the model is LM3 UU), and the linear bearing 3 can roll along the axial direction of the handle 2. As shown in fig. 2, the first seat body 4 and the second seat body are schematic diagrams of the installation structure of the seat bodies, the first seat body 4 is welded on the right side wall surface of the linear bearing 3, the servo electric cylinder 5 is arranged on the right side of the first seat body 4, and the second seat body 6 is welded on the telescopic rod of the servo electric cylinder 5. Referring to fig. 3, which is a partial structural schematic view of the present application, two flanges of the second seat body 6 are connected with the first seat body 4 through a bearing; the second seat body 6 is connected with a rotating shaft 7, second gear teeth 13 are concentrically fixed in the middle of the rotating shaft 7, first gear teeth 12 are fixed on the first seat body 4, and the first gear and the second gear teeth 13 are meshed and matched; according to actual needs, the servo electric cylinder 5 can be installed on the ground through a frame body (a structure with the frame body is shown in fig. 6); a worm 8 is concentrically fixed at the tail end of the rotating shaft 7, a worm wheel 9 is connected to the side wall of the first seat body 4, the worm wheel 9 and the first gear teeth 12 are concentrically and collinearly arranged, and the worm wheel 9 and the worm 8 are meshed and matched.

The working principle of the application is as follows: as shown in fig. 4, which is a schematic view of a motion state structure of the driving handle 2 of the present application, first, the servo electric cylinder 5 drives the telescopic rod to extend, and the second seat body 6 on the telescopic rod pushes the first seat body 4 to move leftward; seat body 4 indirectly promotes handle 2 through linear bearing 3 and removes left, simultaneously because the fixed reason of the bottom of handle 2 and the switching of valve body 1, when linear bearing 3 promoted handle 2 and removed, linear bearing 3 realized on handle 2 and slided the removal, and then leads to handle 2 upset left. Then, when the first seat body 4 (the first gear teeth 12) is turned over, the first gear teeth 12 drive the rotating shaft 7 to rotate rightwards through the second gear teeth 13, the rotating shaft 7 drives the worm 8 to rotate rightwards, and the worm 8 drives the worm wheel 9 on the first seat body 4 to rotate leftwards; when the handle 2 stops overturning without external force, the worm wheel 9 and the worm 8 can lock the hinged position of the first seat body 4 and the second seat body 6.

According to the manual reversing valve, the handle 2 of the manual reversing valve can be remotely adjusted by combining the servo electric cylinder 5, the linear bearing 3 and the hinged relation between the two seat bodies, so that the step that workers arrive at the site to adjust the manual reversing valve is omitted, the labor is saved, the labor cost is reduced, and the working efficiency is improved; this application combines the meshing of the 9 worms of worm wheel 8 and the meshing of two teeth of a cogwheel simultaneously, can in time lock two pedestals that rotate a definite position, avoids the unexpected rotation of articulated department of two pedestals to cause the upset of handle 2 to the upset of avoiding handle 2 causes the unexpected opening of valve body 1, closes, strengthens the security performance of this application.

Further, in order to avoid the phenomenon that the slippage appears when linear bearing 3 moves on handle 2, based on this, this application has designed a novel handle 2, and concrete structure is as follows.

As shown in fig. 5, the novel handle 2 includes a blocking body 201, a rectangular hole 202 is formed in a terminal surface of the handle 2, the blocking body 201 is arranged on one side of the rectangular hole 202, a rectangular strip 203 is welded on the blocking body 201, the rectangular strip 203 is in splicing fit with the rectangular hole 202, a threaded hole is formed in a side end penetrating through the rectangular hole 202, and a positioning screw 204 is in fit with the threaded hole. When in use, firstly, the rectangular strip 203 on the baffle body 201 is inserted into the rectangular hole 202; then, the positioning screw 204 passes through the threaded hole to define the blocking body 201, and on the other hand, the plane of the rectangular strip 203 and the rectangular hole 202 is easier to generate friction force with the end of the positioning screw 204. Meanwhile, the blocking body 201 and the positioning screw 204 are detachable, so that the subsequent linear bearing 3 can be conveniently and smoothly taken down from the handle 2.

Further, when linear bearing 3 need break away from handle 2, the manual separation is comparatively extravagant physical power, and based on this, this application has designed a elevation structure 10.

As shown in fig. 6, the lifting structure 10 includes a track 1001, a motor is installed in the track 1001, a lead screw 1002 is connected to a rotation shaft of the motor, the lead screw 1002 is vertically disposed, a plate body is connected to the lead screw 1002 through a thread, and the plate body and the track 1001 are slidably disposed. Principle of use of the lifting structure 10: when the device is used, firstly, the motor is started, and the motor drives the screw cylinder 1002 to rotate; then, the plate is lifted by the restraint of the screw and the rail 1001, and the plate is smoothly pulled out of the handle 2 through the servo electric cylinder 5.

Further, servo electronic jar 5 in the use, unexpected malfunctioning phenomenon can appear, in order to avoid above-mentioned unexpected condition probably to cause the risk of handle 2 upset, on this basis, this application has designed a insurance structure 11, and concrete structure is as follows.

As shown in fig. 7, the safety structure 11 includes an electric telescopic cylinder 1101, the electric telescopic cylinder 1101 is provided on the surface of the valve body 1, and a clamp 1102 is provided on the telescopic end of the electric telescopic cylinder 1101. It is noted that since the handle 2 is disposed vertically in most cases, the electric telescopic cylinder 1101 in the present application is limited only to the handle 2 disposed vertically. The working principle of the safety structure 11 is as follows: the electric telescopic cylinder 1101 carries out secondary limitation on the vertically arranged handle 2 through a push clamp 1102, and the safety of the application is further enhanced.
