Description
Technical Field
[0001] The utility model relates to the technical field of building construction, in particular to a supporting device for crane traveling operation. Background Art
[0002] In modern building construction, the basement structure is an important part of the building foundation. Its design and construction quality directly affect the safety and stability of the entire building. The basement top plate, as the upper covering layer of the basement structure, not only bears the weight of the upper structure, but also needs to meet the needs of temporary loads during construction, such as crane operations. Figure 1 As shown, the basement roof includes a main beam 11, a secondary beam 12, and a concrete slab 13 laid on the main beam 11 and the secondary beam 12. The main beam 11 and the secondary beam 12 are crisscrossed to form a mesh structure to support the concrete slab 13.
[0003] There are various types of truck cranes, which can be used in different occasions. When performing hoisting operations on the basement ceiling, truck cranes are the preferred type of crane due to their high mobility and flexibility. Truck cranes integrate driving and lifting functions, and can quickly transfer work locations and adapt to different working environments. Compared with crawler cranes or tower cranes, truck cranes do not require complicated assembly and disassembly processes, which greatly improves construction efficiency. Its built-in support system (such as outriggers) can be set up in a short time and put into operation quickly, which is very suitable for hoisting needs on the basement ceiling where space is limited and time is tight.
[0004] However, if the truck crane moves and operates directly on the top plate of the basement, the concentrated pressure on the tires and legs of the truck crane may easily cause excessive local stress on the concrete slab, resulting in cracking or even collapse of the concrete slab, or great stress concentration may be formed at the junction or supporting points of the main beam and secondary beam, causing cracking of the beam or even structural failure of the beam, seriously affecting the safety and stability of the entire building.
[0005] Therefore, there is an urgent need for a support device for crane travel operation, which is used to disperse the tire pressure and leg pressure when the crane is traveling and operating, and ensure the safety and stability of the building. Utility Model Content
[0006] The utility model is intended to provide a supporting device for crane traveling operation, so as to solve the technical problem in the prior art that the tire pressure and the leg pressure of the automobile crane are concentrated, resulting in the destruction of the structure of the basement top plate, affecting the safety and stability of the entire building.
[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0008] A support device for crane travel operation comprises a travel channel and a plurality of working positions arranged along the length direction of the travel channel, wherein the width of the travel channel matches the width of the truck crane; a support assembly is arranged at the working position, wherein the support assembly comprises at least two roadbed boxes, and the roadbed boxes are distributed one to one on both sides of the travel channel.
[0009] The principle and beneficial effects of this program:
[0010] In actual application, the entire supporting device is arranged on the top plate of the basement, and the walking channel is arranged along the driving route of the automobile crane. The automobile crane walks on the walking channel to realize the position conversion from one working position to another working position; the automobile crane performs hoisting operation at the working position, and when the automobile crane performs hoisting operation, the legs on both sides are respectively supported on the roadbed boxes on both sides of the walking channel.
[0011] In this solution, when the truck crane is moving, the tires of the truck crane are supported by the walking channel, and the contact area between the walking channel and the basement roof is larger than the contact area between the tires of the truck crane and the basement roof; when the truck crane is operating, the legs of the truck crane are supported by the roadbed box of the supporting assembly, and the contact area between the roadbed box and the basement roof is larger than the contact area between the legs of the truck crane and the basement roof. In this way, the pressure concentration of the tires of the truck crane and the legs can be effectively reduced, and the structural damage of the basement roof can be avoided. Specifically, excessive local force on the concrete slab can be avoided, thereby avoiding cracking or even collapse of the concrete slab. At the same time, extreme stress concentration can be avoided at the junction or support point of the main beam and the secondary beam, thereby avoiding cracking of the beam body or even causing structural failure of the beam, which is beneficial to ensuring the safety and stability of the overall building.
[0012] Preferably, as an improvement, the length of the roadbed box is not less than twice the distance between the main beam and the adjacent secondary beam, and the middle position of the roadbed box is supported on the main beam, and both ends of the roadbed box are supported on the secondary beams.
[0013] Beneficial effect: This scheme sets the length of the roadbed box to be no less than twice the distance between the main beam and the adjacent secondary beam, which can ensure that when the middle position of the roadbed box is supported on the main beam, the two ends of the roadbed box can be supported on the secondary beam. In this way, the weight of the roadbed box and the dynamic load during the operation of the truck crane can be dispersed to the main beam and the secondary beam, thereby reducing the direct pressure on the non-beam area of the basement roof, protecting the integrity of the basement roof, preventing the concrete slab from cracking and other damage, and extending the service life of the basement roof.
[0014] In addition, the main beam is usually designed to be wider and thicker than the secondary beam, and has a stronger bearing capacity. Supporting the middle position of the roadbed box on the main beam can better utilize the load-bearing capacity of the main beam, increase the stability of the entire support assembly, prevent displacement or overturning during operation of the truck crane, and ensure the stability and safety of the operation.
[0015] Preferably, as an improvement, a protective layer is provided between the walking passage and the basement top plate, and between the roadbed box and the basement top plate.
[0016] Beneficial effects: This solution sets a protective layer at the bottom of the walking channel and the roadbed box. On the one hand, the protective layer can further disperse the concentrated load transmitted to the basement roof by the walking channel and the roadbed box, reduce the pressure per unit area, avoid local overload damage to the basement roof, and protect the integrity and safety of the basement structure; on the other hand, the walking channel and the roadbed box are in direct contact with the basement roof. Long-term friction may cause wear on the surface of the concrete slab. The protective layer acts as a buffer to reduce the wear of direct contact and extend the service life of the basement roof.
[0017] Preferably, as an improvement, the protective layer is a plain soil layer.
[0018] Beneficial effects: This solution uses a bare soil layer as a protective layer. In addition to avoiding local overload damage and extending the service life of the basement roof as mentioned above, the bare soil can also increase the friction between the walking channel and the basement roof, as well as between the roadbed box and the basement roof, preventing the walking channel from sliding when the truck crane is moving. It can also prevent the roadbed box from shifting under the weight of the legs, ensuring the stability and safety of the truck crane's movement and operation.
[0019] Preferably, as an improvement, an anti-skid pad is provided on the top of the roadbed box at a position corresponding to the vehicle crane legs, and the size of the anti-skid pad matches the size of the vehicle crane legs.
[0020] Beneficial effects: This solution sets an anti-skid pad between the roadbed box and the truck crane outrigger. On the one hand, the anti-skid pad can effectively increase the friction between the contact surface of the roadbed box and the outrigger, and prevent the truck crane from slipping during operation or due to external forces even in a humid or oily environment, thereby ensuring operation safety; on the other hand, the anti-skid pad helps to distribute the outrigger pressure more evenly to the roadbed box, reduce deformation or damage caused by local high pressure, and ensure the stability and reliability of the support assembly.
[0021] Preferably, as an improvement, the anti-slip pad is a rubber pad.
[0022] Beneficial effects: This solution uses rubber pads as anti-slip pads, which not only play the above-mentioned anti-slip and pressure dispersion roles, but also serve as a buffer layer between the outriggers and the roadbed box, reducing the impact force and wear when the outriggers are in direct contact with the hard roadbed box, protecting the outrigger surface from scratches or wear, and at the same time avoiding damage to the roadbed box due to uneven force or direct impact, thereby extending the service life of the outriggers and the roadbed box.
[0023] Preferably, as an improvement, the number of the roadbed boxes is the same as the number of the truck crane legs, and the roadbed boxes and the truck crane legs are arranged one to one.
[0024] Beneficial effect: This solution sets up a roadbed box for each leg of the truck crane for support. Compared with the method of setting up a roadbed box to support multiple legs on one side of the truck crane, it can more accurately control and disperse the load of a single leg, further reduce the risk of local overload of the basement roof, ensure the safety of the truck crane operation, and the safety and stability of the entire building.
[0025] In addition, the one-to-one independent support method can ensure that each leg can fully contact the basement ceiling. Even if the basement ceiling is uneven, the overall level and stability of the truck crane can be achieved by adjusting the roadbed boxes under each leg, which is beneficial to improving the anti-overturning ability of the truck crane during operation.
[0026] Preferably, as an improvement, the walking passage is a walking passage paved with steel plates.
[0027] Beneficial effects: This scheme uses steel plates to pave the walking path. On the one hand, the steel plates have high strength and rigidity, which can effectively disperse the pressure of the car crane tires and prevent the concrete slab of the basement top plate from cracking or even collapsing due to excessive local force. On the other hand, the laying and removal of steel plates are relatively simple and quick, and the position of the walking path can be quickly adjusted or rearranged according to construction needs, which is conducive to improving construction efficiency.
[0028] In addition, steel plate is a durable material that can be reused many times. Compared with disposable materials, it is more economical and environmentally friendly, which helps to reduce construction costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The following is further described in detail through specific implementation methods:
[0035] The reference numerals in the drawings of the specification include: main beam 11, secondary beam 12, concrete slab 13, walking channel 2, working position 3, roadbed box 4, protective layer 5, anti-slip mat 6, car crane 7, and outrigger 8.
[0036] A support device for crane travel operation, arranged as shown in the following Figure 1 The basement roof is used to support the mobile crane when it is moving and working, so as to avoid damage to the structure of the basement roof. The basement roof includes a main beam 11, a secondary beam 12, and a concrete slab 13 laid on the main beam 11 and the secondary beam 12. The main beam 11 and the secondary beam 12 are arranged in a crisscross pattern to form a mesh structure to support the concrete slab 13.
[0037] Example 1
[0038] A support device for crane travel operation, as shown in the attached Figure 2 As shown, it includes a walking channel 2 and a plurality of working positions 3 arranged along the length direction of the walking channel 2. The width of the walking channel 2 matches the width of the automobile crane 7, that is, the width of the walking channel 2 is greater than or equal to the width of the automobile crane 7, so as to ensure that the automobile crane 7 can smoothly walk on the walking channel 2. In this embodiment, the walking channel 2 is a walking channel 2 paved with steel plates. The steel plates with high strength and rigidity can effectively disperse the concentrated pressure of the tires of the automobile crane 7 and protect the basement roof structure from being damaged. In addition, the laying and removal of the steel plates are relatively simple and quick, which is conducive to improving construction efficiency.
[0039] Each operating position 3 is provided with a supporting assembly, such as the attached Figure 3 As shown, the support assembly includes at least two roadbed boxes 4, and the roadbed boxes 4 are distributed one-to-one on both sides of the walking passage 2. Specifically, the number of roadbed boxes 4 is the same as the number of legs 8 of the truck crane 7, and the roadbed boxes 4 are arranged one-to-one with the legs 8 of the truck crane 7, so that the load of a single leg 8 can be more accurately controlled and dispersed, reducing the risk of local overload of the basement top plate. In this embodiment, the number of legs 8 of the truck crane 7 is four, so the number of roadbed boxes 4 is four, and the four roadbed boxes 4 are distributed on both sides of the walking passage 2 in a group of two.
[0040] The length of the roadbed box 4 is not less than twice the distance between the main beam 11 and the adjacent secondary beam 12, and the middle position of the roadbed box 4 is supported on the main beam 11, and the two ends of the roadbed box 4 are supported on the adjacent secondary beams 12 on both sides of the main beam 11. The roadbed box 4 adopts the roadbed box 4 of the prior art, and its structure is not repeated in this embodiment.
[0041] The specific implementation process is as follows:
[0042] Walking: The walking passage 2 is set along the travel route of the automobile crane 7. The automobile crane 7 walks on the walking passage 2 and reaches the working position 3 on the walking passage 2. When the automobile crane 7 is walking, the walking passage 2 supports the tires of the automobile crane 7. Since the contact area between the walking passage 2 and the basement ceiling is larger than the contact area between the tires of the automobile crane 7 and the basement ceiling, the walking passage 2 located between the tires of the automobile crane 7 and the basement ceiling can disperse the pressure of the tires of the automobile crane 7 and then act on the basement ceiling, thereby effectively reducing the pressure concentration of the tires of the automobile crane 7, avoiding the damage to the structure of the basement ceiling, and is conducive to ensuring the service life of the basement ceiling, thereby ensuring the safety and stability of the entire building.
[0043] Operation: The mobile crane 7 is operating at the operation position 3. At this time, the legs 8 of the mobile crane 7 are extended and supported on the roadbed box 4 at the corresponding position, so that the tires of the mobile crane 7 are suspended. That is, during the operation of the mobile crane 7, the roadbed box 4 supports the legs 8 of the mobile crane 7. Since the contact area between the roadbed box 4 and the basement roof is larger than the contact area between the legs 8 of the mobile crane 7 and the basement roof, the roadbed box 4 located between the legs 8 of the mobile crane 7 and the basement roof can disperse the pressure of the legs 8 of the mobile crane 7 before acting on the basement roof, thereby effectively reducing the pressure concentration of the legs 8 of the mobile crane 7, avoiding the damage to the structure of the basement roof, and ensuring the service life of the basement roof, thereby ensuring the safety and stability of the entire building.
[0044] Example 2
[0045] A support device for crane travel operation, as shown in the attached Figure 4 As shown, the difference between it and Example 1 is that a protective layer 5 is provided between the walking passage 2 and the basement top plate, and between the roadbed box 4 and the basement top plate, and the size of the protective layer 5 between the walking passage 2 and the basement top plate is greater than or equal to the size of the walking passage 2 to ensure that the walking passage 2 and the basement top plate are completely separated, and the size of the protective layer 5 between the roadbed box 4 and the basement top plate is greater than or equal to the size of the roadbed box 4 to ensure that the roadbed box 4 and the basement top plate are completely separated. In this way, the concentrated load transmitted to the basement top plate by the walking passage 2 and the roadbed box 4 can be effectively dispersed through the protective layer 5, the integrity and safety of the basement structure can be protected, and the wear of the walking passage 2 and the roadbed box 4 in direct contact with the basement top plate can be reduced through the buffering effect of the protective layer 5, thereby extending the service life of the basement top plate.
[0046] In this embodiment, the protective layer 5 is a soil layer, that is, a layer of soil is laid between the walking passage 2 and the basement top plate, and between the roadbed box 4 and the basement top plate to form the protective layer 5. Using the soil layer as the protective layer 5, in addition to the above-mentioned role of avoiding local overload damage and extending the service life of the basement top plate, the soil can also increase the friction between the walking passage 2 and the basement top plate, and between the roadbed box 4 and the basement top plate, to prevent the walking passage 2 from sliding when the truck crane 7 is moving, and also prevent the roadbed box 4 from shifting under the weight of the legs 8, thereby ensuring the stability and safety of the truck crane 7 when it is moving and operating.
[0047] Example 3
[0048] A support device for crane travel operation, as shown in the attached Figure 5 As shown, the difference between it and Example 2 is that an anti-skid pad 6 is placed on the top of the roadbed box 4 corresponding to the position of the legs 8 of the automobile crane 7, and the size of the anti-skid pad 6 matches the size of the legs 8 of the automobile crane 7, that is, the size of the anti-skid pad 6 is greater than or equal to the size of the legs 8 of the automobile crane 7, so as to ensure that the anti-skid pad 6 completely separates the legs 8 of the automobile crane 7 from the roadbed box 4, increases the friction between the legs 8 of the automobile crane 7 and the roadbed box 4, prevents the automobile crane 7 from slipping during operation, and distributes the pressure of the legs 8 more evenly to the roadbed box 4, thereby reducing the deformation or damage of the roadbed box 4 caused by local high pressure.
[0049] In this embodiment, a rubber pad is used as the anti-slip pad 6, which not only plays the above-mentioned anti-slip and pressure dispersion role, but the flexible rubber pad can also serve as a buffer layer between the support leg 8 and the roadbed box 4, reducing the impact force and wear when the support leg 8 is in direct contact with the hard roadbed box 4, protecting the surface of the support leg 8 from scratches or wear, and at the same time avoiding damage to the roadbed box 4 due to uneven force or direct impact, thereby extending the service life of the support leg 8 and the roadbed box 4.
[0050] The above is only an embodiment of the utility model, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the utility model, several deformations and improvements can be made, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
