Description

Technical Field

[0001] This utility model relates to the technical field of trolley connecting rods, and in particular to a connecting rod device for a calcium carbide furnace tapping trolley. Background Technology

[0002] With the increasing competition in the calcium carbide industry, reducing calcium carbide costs and improving the market competitiveness of calcium carbide have become one of the central issues in the industry. Currently, the existing calcium carbide furnace tapping trolley transportation system is not enclosed. The calcium carbide industry tapping system uses tracks as the transportation road for the tapped calcium carbide. The tracks are distributed around the furnace body, and the winch pulls the trolley to achieve transportation.

[0003] Chinese utility model CN217275608U describes a connecting rod device for a calcium carbide furnace tapping trolley. The device works by setting a support plate and a connecting ring between two trolleys. After the connecting ring is inserted into the support plate, it pushes a stop rod to rotate until the stop rod falls into the connecting ring, thus preventing the connecting ring from being pulled out of the support plate and completing the installation.

[0004] However, in the existing device, after installation, the stop bar has a large amount of room to move inside the connecting ring, causing it to rotate left and right. Simultaneously, the connecting ring also extends and retracts inside the support plate, impacting the stop bar and resulting in insufficient stability after installation. Therefore, a more stable linkage device was designed to address the aforementioned problems. Utility Model Content

[0048] Given the current state of the technology, the explanation of existing defects

[0049] like Figure 1-5 As shown, this utility model embodiment provides a connecting rod device for a calcium carbide furnace tapping trolley. The connecting rod device includes: a slide rail 11, on which a first trolley 12 is slidably mounted; a second trolley 13, slidably mounted on the top of the slide rail 11; a connecting assembly 2 is provided between the first trolley 12 and the second trolley 13, the connecting assembly 2 including: a rod 21, rotatably mounted on one side of the second trolley 13; a groove 22, formed on the outer wall of the rod 21; a cylinder 23, rotatably mounted on one side of the first trolley 12; and a housing 24, rotatably mounted on the outer wall of one end of the cylinder 23. A rectangular shell 25 is fixedly disposed on the outer wall of one end of the cylinder 23; a spring 26 is disposed inside the rectangular shell 25; a slider 27 is slidably disposed inside the rectangular shell 25 and connected to the bottom end of the spring 26; a connecting rod 28 is rotatably connected at both ends to the inner wall of the shell 24 and one end of the slider 27; a locking block 29 is disposed at the bottom of the slider 27, and the bottom end of the locking block 29 penetrates through the outer wall of the cylinder 23 and is inserted into the interior of the groove 22; both the shell 24 and the insert rod 21 are provided with limiting components 3 to limit the rotation of the shell 24.

[0050] In use, simply move the trolley 12 and trolley 23 closer together, insert the rod 21 on one side of trolley 23 into the cylinder 23 on one side of trolley 12. Simultaneously, one end of the rod 21 will press the locking block 29 back into the rectangular shell 25, pushing the slider 27 upwards and compressing the spring 26. Once the bottom end of the locking block 29 aligns with the groove 22, the spring 26 will rebound, pushing the bottom end of the locking block 29 into the groove 22. At this point, the flat design on one side of the locking block 29 prevents the rod 21 from detaching from the cylinder 23. When disassembly is required, simply control the housing 24 to rotate. As the housing 24 rotates, the inner wall will pull the connecting rod 28 to rotate, thereby causing the slider 27 to slide upward inside the rectangular housing 25, which will cause the bottom locking block 29 to disengage from the groove 22, releasing the restriction on the insertion rod 21. The insertion rod 21 can then be pulled out from inside the cylinder 23 to complete the disassembly. The trolley 12 and trolley 23 move to the discharge port of the calcium carbide furnace via the bottom slide rail 11, which can collect the material discharged from the discharge port into the interior and transport it out using the bottom slide rail.

[0051] Furthermore, insert rods 21 and cylinders 23 are pre-installed on both sides of the trolley, making it more convenient as there is no need to connect the two ends during the connection process.

[0052] Furthermore, during connection, it is only necessary to control the insertion rod 21 to be inserted into the cylinder 23, and the locking block 29 will automatically engage with the groove 22, which is more convenient than the existing manual insertion method of the pin.

[0053] Furthermore, vibrations are inevitable during the transportation of materials. In this application, when the locking block 29 engages with the groove 22, the spring 26 rebounds and pushes, making it less likely to disengage during vibrations. At the same time, the locking block 29 is located inside the housing 24 and is less susceptible to damage.

[0054] Furthermore, the rectangular shell 25 is provided with four sets.

[0055] When in use, the four-group design allows four locking blocks 29 to be inserted into the recess 22, which can better restrict the insertion rod 21.

[0056] Furthermore, the connecting component 2 also includes an arc-shaped block 211 disposed at one end of the insertion rod 21.

[0057] When in use, the arc-shaped block 211 is designed to reduce friction between components when it comes into contact with the card block 29.

[0058] Furthermore, the connecting component 2 also includes a rubber pad 231 disposed on the inner side wall of the cylinder 23.

[0059] When in use, the rubber pad 231 is designed to act as a buffer when the insertion rod 21 is inserted into the cylinder 23.

[0060] Furthermore, the connecting component 2 also includes: multiple levers 241, all disposed on the outer side wall of the housing 24.

[0061] The lever 241 is designed for easy gripping and convenient control of the rotation of the housing 24.

[0062] Furthermore, the limiting component 3 includes: a ring body 31, fixedly disposed on one side of the housing 24; a positioning hole 32, formed on one side of the ring body 31; a movable ring 33, sleeved on the outer side wall of the insertion rod 21; a protrusion 34, disposed on the outer side wall of the insertion rod 21 and slidably connected to the movable ring 33, limiting the rotation of the movable ring 33; and a protrusion 35, disposed on one side of the movable ring 33.

[0063] After the connection is completed, in order to ensure the firmness, the housing 24 needs to be restricted to prevent rotation. Simply slide the moving ring 33 to move on the insertion rod 21 and fit it against the ring body 31. Insert the protrusion 35 on one side of the moving ring 33 into the positioning hole 32. After that, restrict the ring body 31. Because the ring body 31 is connected to the housing 24, it can restrict the rotation of the housing 24 and maintain the engagement stability of the locking block 29 and the groove 22.

[0064] Furthermore, the limiting component 3 also includes a cone 36 disposed at one end of the protrusion 35.

[0065] When in use, the design of the cone 36 makes it relatively easier to insert the protrusion 35 into the positioning hole 32.

[0066] Furthermore, the limiting component 3 also includes a magnetic block 37, which is embedded in one side of the ring body 31 and the movable ring 33, and the magnetic blocks 37 are magnetically attracted to each other.

[0067] When in use, after the moving ring 33 and the ring body 31 are attached, the magnetic block 37 attracts them magnetically, making it difficult for the moving ring 33 and the ring body 31 to separate.

[0068] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
