Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic valve sleeve processing, in particular to a counting mechanism for hydraulic valve sleeve processing and conveying. Background Technique

[0002] A hydraulic valve is an automatic component operated by pressure oil and can be used for remotely controlling the on-off of the oil, gas, and water pipe systems of a hydropower station. It mainly consists of a valve core, a valve sleeve, a spring, and a sealing ring. During the processing of the hydraulic valve sleeve, it is conveyed and moved through a conveying device. Usually, a counting device is installed on the conveying device to count the number of conveyed hydraulic valve sleeves. Some counting devices include a mounting base, and a counter is provided on the upper side of the mounting base. During use, the mounting base is first fixed to the hydraulic valve sleeve conveying device through the threaded holes on the mounting base with bolts. Subsequently, the hydraulic valve sleeve moves through the conveying device, and then the counter operates to count the number of passing hydraulic valve sleeves. However, this device is fixed to the hydraulic valve sleeve conveying device through multiple bolts. When each bolt is fixed, the staff needs to use pliers to rotate the bolt for multiple turns, and the operation is relatively cumbersome. At the same time, during the conveying of the hydraulic valve sleeve, the detection and counting unit of the device is set as a group, and the counting accuracy of the hydraulic valve sleeve needs to be improved. Content of the Utility Model

This device is fixed to the left end of the hydraulic valve sleeve processing and conveying device quickly through elastic clamping and threaded connection reinforcement, and the operation is convenient and fast. At the same time, the device counts and compares the number of hydraulic valve sleeves through two groups of counting elements, effectively improving the counting accuracy of the device during the processing and conveying of hydraulic valve sleeves, and can effectively solve the problems in the background technique.

[0004] To achieve the above purpose, the utility model provides the following technical scheme: A counting mechanism for hydraulic valve sleeve processing and conveying, including a belt conveyor and a counting quick-installation mechanism;

The arc-shaped extrusion seat is cooperatively installed with the belt conveyor. Uniformly distributed springs are provided between the arc-shaped extrusion seat and the bottom wall of the mounting frame.

[0010] Furthermore, rubber pads are provided on the upper side of the arc-shaped extrusion seat and the top wall of the mounting frame. The rubber pads increase the contact friction force to avoid relative sliding between the mounting frame and the arc-shaped extrusion seat and the belt conveyor. At the same time, the rubber pads avoid the phenomenon of extrusion deformation of the fixed surface between the counting mechanism and the belt conveyor when they are fixed.

[0011] Furthermore, reflective sheets are provided on the right walls of the suspension frames. The reflective sheets are all cooperatively installed with the adjacent laser rangefinders to reflect the optical signals emitted by the laser rangefinders.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-3 , this embodiment provides a technical solution: a counting mechanism for processing and conveying hydraulic valve sleeves, including a belt conveyor 1 and a counting quick installation mechanism 4;

[0022] Belt conveyor 1: An installation frame 2 is installed on its left side. Suspended frames 6 are symmetrically arranged on the upper side of the installation frame 2. Laser rangefinders 7 are provided on the left walls of the suspended frames 6. A single-chip microcomputer 3 is provided on the left side of the installation frame 2. The input end of the single-chip microcomputer 3 is electrically connected to an external power supply. The input end of the belt conveyor 1 is electrically connected to the output end of an external control switch. The laser rangefinders 7 are both bidirectionally electrically connected to the single-chip microcomputer 3. Reflective sheets 8 are provided on the right walls of the suspended frames 6. The reflective sheets 8 are both installed in cooperation with the adjacent laser rangefinders 7. A display screen 9 is provided on the left side of the installation frame 2. The input end of the display screen 9 is electrically connected to the output end of the single-chip microcomputer 3. After the counting mechanism and the hydraulic valve sleeve processing and conveying device are fixed, the external control switch starts the belt conveyor 1 to convey the hydraulic valve sleeve through the belt. At the same time, the single-chip microcomputer 3 starts the laser rangefinders 7. The laser rangefinders 7 emit optical signals that are reflected to the initial position after irradiating the reflective sheets 8. The distance between the laser rangefinders 7 and the adjacent reflective sheets 8 is obtained through the propagation time and speed of the optical signals, and the measurement result is transmitted to the single-chip microcomputer 3 in the form of an electrical signal. At this time, the distance measured by the laser rangefinder 7 is the initial distance. When the hydraulic valve sleeve passes through the space between the laser rangefinder 7 and the reflective sheet 8 through the belt conveyor 1, the measurement result of the laser rangefinder 7 obtained by the single-chip microcomputer 3 changes until the measurement result returns to the initial distance value again. The single-chip microcomputer 3 increments the count of the hydraulic valve sleeve by one. In this way, the counting of the hydraulic valve sleeve processing and conveying is carried out. And the device uses two groups of laser rangefinders 7, so that the counting of the hydraulic valve sleeve processing and conveying can be carried out twice. The single-chip microcomputer 3 compares the two counting results, thereby improving the counting accuracy of the device for the hydraulic valve sleeve processing and conveying. The single-chip microcomputer 3 transmits the counting result of the hydraulic valve sleeve processing and conveying to the display screen 9 in the form of an electrical signal for display for the staff to view. The device counts and compares the number of hydraulic valve sleeves through two groups of counting elements, effectively improving the counting accuracy of the device during the processing and conveying of the hydraulic valve sleeve;

[0023] Counting Quick Installation Mechanism 4: It includes a telescopic column 41, a spring 42, and an arc-shaped extrusion seat 43. The telescopic columns 41 are evenly arranged on the bottom wall of the mounting frame 2. An arc-shaped extrusion seat 43 is provided at the upper end of the telescopic end of the telescopic column 41. The arc-shaped extrusion seat 43 is cooperatively installed with the belt conveyor 1. Uniformly distributed springs 42 are provided between the arc-shaped extrusion seat 43 and the bottom wall of the mounting frame 2. The springs 42 are all movably sleeved on the outer ends of the adjacent telescopic columns 41. The counting quick installation mechanism 4 further includes a stud 44, a threaded cylinder 45, an auxiliary reinforcement seat 46, and a handwheel 48. The stud 44 is rotatably connected to the bottom wall of the mounting frame 2 through a bearing. The upper end of the stud 44 is threadedly connected with a threaded cylinder 45. An auxiliary reinforcement seat 46 is provided at the upper end of the threaded cylinder 45. The auxiliary reinforcement seat 46 is cooperatively installed with the arc-shaped extrusion seat 43. A handwheel 48 is provided at the lower end of the stud 44. The counting quick installation mechanism 4 further includes a guide rod 47. The guide rods 47 are symmetrically arranged on the lower side of the auxiliary reinforcement seat 46. The lower ends of the guide rods 47 are all slidably connected to the sliding holes on the bottom wall of the mounting frame 2. Rubber pads 5 are provided on the upper side of the arc-shaped extrusion seat 43 and the top wall of the mounting frame 2. When counting during the processing and conveying of the hydraulic valve sleeve, first, the mounting frame 2 is buckled and slid from left to right along the left edge of the belt conveyor 1. During this process, the arc-shaped extrusion seat 43 contacts and presses against the lower left edge of the belt conveyor 1 through its own arc surface, causing the arc-shaped extrusion seat 43 to be pressed and move downward, and the telescopic end of the telescopic column 41 and the spring 42 to contract. Under the compression elastic force of the spring 42, through the cooperation of the arc-shaped extrusion seat 43 and the top wall of the mounting frame 2, the counting mechanism is initially and quickly installed on the belt conveyor 1. The rubber pads 5 avoid the relative sliding phenomenon between the mounting frame 2 and the arc-shaped extrusion seat 43 and the belt conveyor 1 by increasing the contact friction force. At the same time, the rubber pads 5 avoid the extrusion deformation phenomenon of the fixed surface between the counting mechanism and the belt conveyor 1 when they are fixed. Subsequently, rotate the handwheel 48 to drive the stud 44 to rotate. The stud 44 makes the threaded cylinder 45 drive the auxiliary reinforcement seat 46 to move vertically upward through threaded connection. The auxiliary reinforcement seat 46 moves upward and presses the arc-shaped extrusion seat 43 upward, thereby further improving the installation tightness between the counting mechanism and the belt conveyor 1. It is convenient to use. During the upward movement of the auxiliary reinforcement seat 46, the guide rods 47 slide along the corresponding sliding holes, thereby avoiding the self-rotation phenomenon of the auxiliary reinforcement seat 46 during the vertical movement. This device is fixed by elastic clamping and threaded connection reinforcement, so that the counting mechanism is quickly fixed to the left end of the hydraulic valve sleeve processing and conveying device, and the operation is convenient and fast.

[0024] The working principle of a counting mechanism for processing and conveying hydraulic valve sleeves provided by the present utility model is as follows: When counting the hydraulic valve sleeves during the processing and conveying process, first, the mounting frame 2 is buckled and slid from left to right along the left edge of the belt conveyor 1. During this process, the arc-shaped extrusion seat 43 is in extrusion contact with the lower left edge of the belt conveyor 1 through its arc surface, causing the arc-shaped extrusion seat 43 to be pressed downward, and the telescopic end of the telescopic column 41 and the spring 42 to contract. Under the compressive elastic force of the spring 42, through the cooperation of the arc-shaped extrusion seat 43 and the top wall of the mounting frame 2, the counting mechanism is initially and quickly installed on the belt conveyor 1. The rubber pad 5 increases the contact friction to prevent relative sliding between the mounting frame 2 and the arc-shaped extrusion seat 43 and the belt conveyor 1, and at the same time, the rubber pad 5 prevents the fixed surface between the counting mechanism and the belt conveyor 1 from being extruded and deformed when they are fixed. Subsequently, rotate the handwheel 48 to drive the screw 44 to rotate. The screw 44 is threadedly connected so that the threaded cylinder 45 drives the auxiliary reinforcement seat 46 to move vertically upward. The auxiliary reinforcement seat 46 moves upward and presses the arc-shaped extrusion seat 43 upward, thereby further improving the installation tightness between the counting mechanism and the belt conveyor 1, which is convenient to use. During the upward movement of the auxiliary reinforcement seat 46, the guide rod 47 slides along the corresponding sliding hole to prevent the auxiliary reinforcement seat 46 from rotating during the vertical movement. After the counting mechanism is fixed to the hydraulic valve sleeve processing and conveying device, the external control switch starts the belt conveyor 1 to convey the hydraulic valve sleeve through the belt. At the same time, the single-chip microcomputer 3 starts the laser rangefinder 7. The laser rangefinder 7 emits an optical signal, which is reflected to the initial position after irradiating the reflector 8. The distance between the laser rangefinder 7 and the adjacent reflector 8 is obtained through the propagation time and speed of the optical signal, and the measurement result is transmitted to the single-chip microcomputer 3 in the form of an electrical signal. At this time, the distance measured by the laser rangefinder 7 is the initial distance. When the hydraulic valve sleeve passes through the space between the laser rangefinder 7 and the reflector 8 through the belt conveyor 1, the measurement result of the laser rangefinder 7 obtained by the single-chip microcomputer 3 changes until the measurement result returns to the initial distance value again. The single-chip microcomputer 3 adds one to the count of the hydraulic valve sleeve. In this way, the processing and conveying of the hydraulic valve sleeve are counted. And the device uses two groups of laser rangefinders 7, so that the processing and conveying of the hydraulic valve sleeve can be counted twice. The single-chip microcomputer 3 compares the two counting results to improve the counting accuracy of the device for the processing and conveying of the hydraulic valve sleeve. The single-chip microcomputer 3 transmits the counting result of the hydraulic valve sleeve processing and conveying to the display screen 9 in the form of an electrical signal for display for the staff to view.

[0025] It should be noted that, in the above embodiments, the single-chip microcomputer 3 can adopt MCS-51, the belt conveyor 1 can adopt TD-3 belt conveyor, the laser rangefinder 7 can adopt WH-LRF laser rangefinder, the display screen 9 can adopt JBH686N002, and the single-chip microcomputer 3 controls the laser rangefinder 7 and the display screen 9 to work by using the commonly used methods in the prior art. The external control switch is provided with control buttons corresponding to the belt conveyor 1 for controlling its switch.

[0026] The above are only the embodiments of the present invention, and thus do not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be similarly included in the patent protection scope of the present invention.
