Description

Technical Field

[0001] The utility model relates to the technical field of track plate tooling, in particular to an active rubber track plate sweeping tooling. Background Art

[0002] Double-girder crane generally refers to double-girder bridge crane. Double-girder crane is generally composed of three major parts: mechanical, electrical and metal structure. The appearance of bridge crane is a single-span flat bridge supported at both ends on two parallel overhead rails. Double-girder crane is widely used in indoor and outdoor industrial and mining enterprises, steel and chemical industry, railway transportation, port terminals and logistics turnover departments and places.

[0003] Cranes are developing and being used more and more widely in the market. Modern lifting double-beam cranes usually have lifting effects, and most of them use electric hoists to lift objects.

[0004] When the trolley track of a double-beam crane is laid on the working surface or the ground, fixed track sweeping plates should be installed at both ends of the crane, and the distance between the track sweeping plates and the track surface should not be greater than 10mm. The gantry crane in the company's dock area has an uneven track surface due to the sinking of the foundation over a long period of time. The track sweeping plates are more than 40mm away from the track surface, which is seriously inconsistent with various standards and has no effect and does not meet safety standards. If a fixed track sweeping plate with a diameter less than 10mm is installed, when the crane is driven to an uneven track or a loose track joint, it is very easy to cause the fixed track sweeping plate to collide and deform, making it impossible to clean the garbage on the track and protect the walking rollers of the lifting equipment. To solve this problem, an improved flexible rubber track sweeping plate tooling was studied. Utility Model Content

[0011] In a possible implementation manner, notches are formed on both sides of the lower side of the rubber sheet.

[0012] First, grind the installation position of the fixing plate with a grinding wheel to clean the rust or paint on the protective box; then fix the fixing plate to the surface of the protective box by welding;

[0013] The fixing plate and the mounting plate can be made of two 50x200 flat irons; the rubber sheet can be a 20mm thick rubber skin cut into a T shape (the T-shaped rubber skin can be freely adjusted according to the height of the crane protection box 2 and the top surface of the ground rail 1);

[0014] Ensure that the rubber sheet is less than 10mm from the top surface of the ground rail. When the crane is driven to a place where the ground rail is uneven or the rail joint is loose, the rubber track sweeping plate will bend or push up, which will not affect the safe use of the crane. It is easy to repair if the rubber skin ages severely and breaks.

[0015] Specific assembly process:

[0016] 1. Cut the rubber sheet into a T shape, drill holes in two 50x200 flat irons (i.e. the fixing plate and the mounting plate), connect them with screws, and fix the T-shaped rubber skin of the rubber sheet together;

[0017] 2. Ensure that the distance between the rubber skin and the track surface is less than 10mm;

[0020] In a possible implementation, the groove depth radius of the first installation groove is smaller than the groove depth radius of the second installation groove.

[0021] In a possible implementation, the difference between the radius of the adjusting pressure roller and the groove depth radius of the second installation groove is equal to the thickness of the rubber sheet.

[0023] In a possible implementation, chamfers are provided at the notches of the first slot and the second slot.

[0024] In a possible implementation, the outer ends of the two rotating shafts pass through the fixed shell and are provided with hexagonal heads.

[0025] Beneficial effects compared with the prior art:

[0026] 1. In this solution, the fixing plate and the mounting plate can be made of two 50x200 flat irons; the rubber sheet can be a 20mm thick rubber skin, cut into a T shape (the T-shaped rubber skin can be freely adjusted according to the height of the crane protection box and the top surface of the ground rail); ensure that the rubber sheet and the top surface of the ground rail are less than 10mm. When the crane is driven to an uneven ground rail or the rail joint is loose, the rubber track sweeping plate will bend and deform or push up, which will not affect the safe use of the crane. It is easy to repair if the rubber skin is severely aged and broken;

[0027] 2. In this scheme, the hexagonal sleeve is rotated 180 degrees; the rubber sheet that was originally in a vertical state is constrained by the second mounting groove of the semi-cylindrical surface of the adjusting roller; so that the rubber sheet is bent and just snapped into the inside of the second mounting groove; because the rubber sheet has a certain toughness, the bent part has a stress to restore the verticality, and the rubber sheets on the upper and lower sides of the adjusting roller are bent, so the stresses of the two are balanced, so that the adjusting roller cannot move and remains stationary; by fixing the rubber sheet in the above manner, when the lower end of the rubber sheet is worn, the adjusting roller is rotated 180 degrees to restore the rubber sheet, and then the rubber sheet is moved downward, and finally the adjusting roller is rotated 180 degrees to adjust the rubber sheet; this method is simple and convenient, and does not require disassembly of any components; it greatly improves maintenance efficiency.

[0040] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in the form of examples in conjunction with the accompanying drawings.

[0041] Embodiment 1:

[0042] like Figure 1 and Figure 2 As shown, this embodiment introduces the specific structure of the active rubber track sweeping plate tooling, including a ground rail 1, a fixing device 3, a crane leg 4 and a rubber sheet 5; the ground rail 1 is buried underground, and the upper part of the ground rail 1 is used for the crane leg 4 to walk; a running wheel 41 is arranged under the crane leg 4, and when the running wheel 41 rolls on the top of the ground rail 1, it can drive the crane to run relative to the ground rail 1, thereby moving the hoisted heavy object;

[0043] A protection box 2 is provided on the outer side of the crane leg 4 and close to the upper side of the ground rail 1. The protection box 2 is used to protect the running of the running wheel 41 and the ground rail 1. The main function is to prevent some larger materials from being located on the ground rail 1. The materials can be pushed away by the protection box 2, which will cause the running wheel 41 to derail during operation. At the same time, the running wheel 41 is protected to minimize its exposure to wind and sun.

[0044] The rubber sheet 5 is arranged on both sides of the protection box 2 through the fixing device 3 ( Figure 2 Only one side is shown in the figure); when the crane leg 4 moves back and forth along the ground rail 1, the top of the ground rail 1 can be cleaned by the rubber sheet 5; later, as the rubber sheet 5 and the ground rail 1 wear and become shorter, the rubber sheet 5 can be adjusted downward by the fixing device 3 so that it is always in contact with the top of the ground rail 1, so that it can be used for a long time.

[0045] Embodiment 2:

[0046] This embodiment is an improvement made on the basis of the first embodiment:

[0047] like Figure 3 and Figure 4As shown, the fixing device 3 includes a fixing plate 31 and a mounting plate 32; the fixing plate 31 is fixedly connected to both sides of the protective box 2 along the path of the ground rail 1; preferably, welding is adopted; the mounting plate 32 is fixedly connected to the fixing plate 31 by screws 34; the rubber sheet 5 is arranged between the fixing plate 31 and the mounting plate 32; the rubber sheet 5 is firmly fixed inside the two by tightening the screws 34; so that it cannot be displaced;

[0048] The rubber sheet 5 has notches 51 on both sides below, so that the bottom of the rubber sheet 5 can better fit with the top of the floor rail 1. At the same time, the upper portion is used to assemble with the fixing plate 31 and the mounting plate 32, further increasing the strength of the installation part of the rubber sheet 5 and making it more secure.

[0049] The specific installation method is:

[0050] First, the installation position of the fixing plate 31 is polished by a grinding wheel to clean the rust or paint on the protection box 2; then the fixing plate 31 is fixed to the surface of the protection box 2 by welding;

[0051] The fixing plate 31 and the mounting plate 32 can be made of two 50x200 flat irons; the rubber sheet 5 can be a 20mm thick rubber skin cut into a T shape (the T-shaped rubber skin can be freely adjusted according to the height of the crane protection box 2 and the top surface of the ground rail 1);

[0052] Ensure that the rubber sheet 5 is less than 10mm from the top surface of the ground rail 1. When the crane is driven to the uneven ground rail 1 or the rail joint is loose, the rubber track sweeping plate will bend or push up, which will not affect the safe use of the crane. It is convenient to repair the subsequent rubber skin after severe aging and breaking.

[0053] Specific assembly process:

[0054] 1. Cut the rubber sheet 5 into a T-shape, drill holes in two 50x200 flat irons (i.e., the fixing plate 31 and the mounting plate 32), connect them with screws 34, and fix the T-shaped rubber skin of the rubber sheet 5 together;

[0055] 2. Ensure that the distance between the rubber skin and the track surface is less than 10mm;

[0056] 3. If the rubber sheet 5 is severely aged or broken and needs to be repaired, loosen the screw 34, pull out the T-shaped rubber skin and replace it.

[0057] Embodiment three:

[0060] The fastening assembly 36 is rotatably mounted inside the first mounting groove 351; the fastening assembly 36 includes an adjusting roller 361, which is a semi-cylindrical body, wherein the difference between the radius of the adjusting roller 361 and the groove depth radius of the second mounting groove 352 is equal to the thickness of the rubber sheet 5;

[0061] The two ends of the adjusting roller 361 are respectively fixedly connected with a rotating shaft 362, and the distance between the inner ends of the two rotating shafts 362 is the width of the rubber sheet 5; the outer ends of the two rotating shafts 362 penetrate the fixed shell 35 and are provided with a hexagonal head 363; when the hexagonal head 363 is screwed through the hexagonal sleeve, the adjusting roller 361 can be driven to rotate;

[0062] The upper and lower end surfaces of the fixed shell 35 are provided with a slot 1 353 and a slot 2 354 ; the slot 1 353 and the slot 2 354 are for the rubber sheet 5 to pass through;

[0063] The rotation center of the adjusting pressure roller 361 is located at the position of the long side line connecting the slot 1 353 and the slot 2 354 away from the protection box 2; Figure 9 In the state, the rubber sheet 5 can pass through the slot 1 353 and the slot 2 354 normally without interfering with the adjustment roller 361;

[0064] The slots 1 353 and 2 354 are provided with chamfers 355 at their notches; the chamfers 355 are used to facilitate the insertion of the rubber sheet 5 into the slots 1 353 and 2 354 .

[0065] The installation method of this embodiment is as follows:

[0066] First, the fixed shell 35 is fixed on both sides of the protective box 2 along the path of the ground rail 1; initially, when the rubber sheet 5 is not inserted into the fixed shell 35, the flat part of the adjusting roller 361 is in a horizontal state under the action of gravity; when the rubber sheet 5 is inserted into the fixed shell 35 through the slot 1 353, the lower end extends out of the slot 2 354, so that the lower end of the rubber sheet 5 abuts against the ground rail 1;

[0067] Then, the hexagonal sleeve is rotated 180 degrees, and the adjustment pressure roller 361 is Fig.10state; the rubber sheet 5, which was originally in a vertical state, is constrained by the second mounting groove 352 of the semi-cylindrical surface of the adjusting roller 361; so that the rubber sheet 5 is bent and just snapped into the inside of the second mounting groove 352; because the rubber sheet 5 has a certain toughness, the bent part has a stress to restore the verticality, and the rubber sheets 5 on the upper and lower sides of the adjusting roller 361 are bent, so that the stresses of the two are balanced, so that the adjusting roller 361 cannot move and remains stationary; by fixing the rubber sheet 5 in the above manner, when the lower end of the rubber sheet 5 is worn, the adjusting roller 361 is rotated 180 degrees to restore the rubber sheet 5, and then the rubber sheet 5 is moved downward, and finally the adjusting roller 361 is rotated 180 degrees to adjust the rubber sheet 5; this method is simple and convenient, and no parts need to be disassembled; it greatly improves the maintenance efficiency.
