Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of three-dimensional warehousing, in particular to an overspeed detection device for a stacker. Background Art
[0002] Overspeed protection devices are widely used in equipment with lifting and moving parts, such as stackers, hoists, etc. The common overspeed protection scheme generally directly installs the speed limiter and its travel switch on the top of the equipment. When the travel switch needs to be reset during equipment commissioning and use, personnel are often required to climb to the top to reset it, causing instability; in addition, ordinary speed limiters do not have the function of rope breakage and loose rope detection. Once the wire rope breaks, the speed limiter will lose its overspeed detection ability, causing safety hazards. Therefore, it is of considerable value to provide an overspeed protection device with rope breakage and loose rope detection functions and easy reset. Utility Model Content
[0003] The purpose of the utility model is to provide an overspeed detection device for a stacker to solve the problems of inconvenient debugging of current equipment and lack of rope breaking and loosening detection functions, change the speed limiter to a bottom-mounted installation, change the installation method to clamping with a clamping plate, and add a travel switch to detect the sliding of the speed limiter, so as to detect the rope loosening and breaking. It makes it easier to reset the travel switch, and adds rope breaking and loosening detection functions to the overspeed protection device.
[0004] The technical solution of the utility model is as follows:
[0005] An overspeed detection device for a stacker comprises an equipment body, a fixed pulley is arranged at the top of the side of the equipment body, the fixed pulley is connected to a speed limiter through a wire rope, and the speed limiter is arranged at the bottom of the same side of the equipment body; a speed limiter travel switch and a loose rope detection travel switch are arranged on the speed limiter, and a lifting and lowering moving component is arranged on the wire rope.
[0006] Furthermore, the speed limiter is slidably connected with a sliding connecting plate, which is fixedly connected to the speed limiter bracket and the pressure plate. The speed limiter can slide downward along the sliding connecting plate, touch the loose rope detection travel switch, and trigger the alarm braking.
[0007] Furthermore, the fixed pulley, the speed limiter bracket and the pressure plate are fixedly connected to the equipment body through the bracket.
[0008] Furthermore, the sliding connecting plate is L-shaped.
[0009] Furthermore, the speed limiter travel switch is arranged above the speed limiter, and the loose rope detection travel switch (8) is arranged on the side of the speed limiter.
[0010] Furthermore, a counterweight is provided under the speed limiter.

[0017] Figure numerals: 1-fixed pulley, 2-wire rope, 3-lifting moving part, 4-speed limiter travel switch, 5-speed limiter, 6-counterweight, 7-speed limiter bracket and pressure plate, 8-loose rope detection travel switch, 9-sliding connecting plate. DETAILED DESCRIPTION
[0018] It should be noted that relational terms such as "first" and "second" are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.
[0019] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.
[0020] See also Figure 1An overspeed detection device for a stacker includes a device body, a fixed pulley 1 is arranged at the top of the side of the device body, the fixed pulley 1 is connected to a speed limiter 5 through a steel wire rope 2, and the speed limiter 5 is arranged at the bottom of the same side of the device body; a speed limiter travel switch 4 and a rope loosening detection travel switch 8 are arranged on the speed limiter 5, and a lifting and lowering moving part 3 is arranged on the steel wire rope 2. The speed limiter is changed to a bottom-mounted installation, the installation method is changed to a clamping plate, and a travel switch is added to detect the sliding of the speed limiter, so as to detect the rope loosening and breaking. It makes it easier to reset the travel switch, and adds rope breaking and loosening detection functions to the overspeed protection device.
[0021] The speed limiter 5 is slidably connected with a sliding connecting plate 9, which is fixedly connected to the speed limiter bracket and the pressure plate 7. The speed limiter 5 can slide downward along the sliding connecting plate 9, touch the loose rope detection travel switch 8, and trigger the alarm brake.
[0022] The fixed pulley 1, the speed limiter bracket and the pressure plate 7 are fixedly connected to the equipment body through the bracket.
[0023] The sliding connection plate is L-shaped.
[0024] The speed limiter travel switch 4 is arranged above the speed limiter 5 , and the loose rope detection travel switch 8 is arranged on the side of the speed limiter 5 .
[0025] A counterweight 6 is also provided under the speed limiter 5 .
[0026] The fixed pulley 1 fixed on the top of the equipment, the wire rope 2, and the speed limiter 5 located at the bottom of the equipment together constitute a certain pulley group. The speed limiter is not directly installed on the equipment, but assembled on the L-shaped sliding connecting plate 9. During installation, the staff will put the wire rope on the speed limiter 5, assemble it with the counterweight 6 and the L-shaped sliding connecting plate 9 as a whole, and clamp it with the speed limiter bracket and pressure plate 7 fixed at the bottom of the equipment, so that the traction force of the wire rope and the friction provided by the clamping of the pressure plate are balanced with the deadweight of the speed limiter and the counterweight.
[0027] How it works
[0028] During operation, the lifting and moving part 3 that needs speed limit is used to pull the wire rope. If the speed of the lifting and moving part 3 exceeds the set value, the speed limiter 5 will trigger the speed limiter travel switch 4, and the alarm will be braked. After the fault is eliminated, the staff can directly press the reset button on the speed limiter travel switch 4 on the ground to reset it.
[0029] When the wire rope 2 is loose or broken, due to insufficient traction, the speed limiter 5, the counterweight 6, and the sliding connecting plate 9 will slide downward, touch the loose rope detection travel switch 8, and trigger the alarm brake.
[0030] Compared with the common overspeed protection device, this structure adds the broken rope and loose rope detection functions, which improves the reliability;
[0031] The speed limiter is changed to a bottom-mounted type, which makes it easier for workers to reset the travel switch on the ground, making debugging and use more convenient;
[0032] The counterweight-type tensioning wire rope is adopted, which is easy to install and facilitates the long-term and effective tensioning of the wire rope;
[0033] The sliding design of the counterweight and speed limiter can avoid malfunction caused by shaking when the equipment starts and stops.
[0034] The above-mentioned embodiments only express the specific implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the protection scope of the present application. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the technical solution concept of the present application, and these all belong to the protection scope of the present application.
