Description

Technical Field

[0001] This utility model relates to the field of tower crane base technology, and specifically discloses an assembled tower crane base. Background Technology

[0002] Tower cranes are commonly used equipment on construction sites. When installing existing tower crane bases, anchor bolts or embedded sections are usually pre-embedded. At the same time, it is necessary to ensure that the anchor bolts or embedded sections are perpendicular to the concrete base to ensure that they can be fixed to the base later. Existing embedded sections can only be used once and cannot be reused, which will result in waste.

[0003] For example, utility model patent No. 2020205789715 discloses a novel wind-resistant and earthquake-resistant tower crane base, including a base. A cylindrical support platform is vertically and movably installed in the center of the top surface of the base. A horizontally arranged fixing plate is fixedly installed on the top surface of the support platform. A horizontally arranged mounting plate is fixedly installed on the top surface of the fixing plate by several bolts. Vertically arranged support columns are fixedly installed at the four corners of the top surface of the mounting plate. A connecting plate is horizontally arranged at the top of the support column. The top of each support column is fixedly connected to the four corners of the bottom surface of the connecting plate. A sleeve is fixedly fitted on the upper part of the column body of each support column, and a windproof component is fixedly installed on the outside of the sleeve body. In the case of existing tower crane bases, because they are not completely composed of rigid connections, some vibrations cannot be offset, resulting in increased swaying at the top of the tower crane. This causes greater psychological pressure on the operators when operating the tower crane, which is not conducive to their work. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide an assembled tower crane base to solve the technical problem that existing tower crane bases, when used to counteract vibrations, cause the top of the tower crane to sway, which is not conducive to the work of the staff.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an assembled tower crane base, including a cross support frame, on which a counterweight mechanism is provided. The counterweight mechanism includes a first counterweight block and a second counterweight block. Wedge blocks are provided on both sides of the first and second counterweight blocks. Two sets of wedge blocks on the first counterweight block are placed on the cross support frame, and two sets of wedge blocks on the second counterweight block are placed on several sets of wedge blocks on the first counterweight block. Several sets of support mechanisms are provided on both the first and second counterweight blocks. Abutment mechanisms are provided at each of the four corners of the cross support frame. The counterweight mechanism can fix the cross support frame to the concrete base without the need to cast embedded parts on the concrete base, making construction more convenient and reducing material waste.

[0006] Furthermore, the supporting mechanism includes a fixed block with a detachable movable block. Both the movable block and the fixed block have V-shaped grooves. The fixed block is placed on the cross support frame. U-shaped blocks are fastened to both sides of the fixed block, and the other ends of the two sets of U-shaped blocks are fastened to the cross support frame. The cross support frame has several sets of reinforcing ribs, and both sets of U-shaped blocks are in contact with these reinforcing ribs. Two sets of limiting blocks are fixedly connected to both the movable block and the fixed block. The limiting block on the fixed block is slidably fastened to the movable block. An extension block is provided at the bottom of the movable block, and a one-way moving component is provided between the fixed block and the extension block. The supporting mechanism can support the first and second counterweight blocks, preventing displacement and ensuring that the first and second counterweight blocks always fix the cross support frame, thus ensuring the safe operation of the tower crane.

[0007] Furthermore, the unidirectional movement component includes a first locking block, and a second fixing groove is formed on the movable block / fixed block. The first locking block is slidably engaged in the second fixing groove. A spring is provided inside the first locking block, and both ends of the spring contact the bottom of the first locking block and the bottom of the second fixing groove, respectively. A plurality of sets of locking slots are formed on the extension block, and the first locking block is engaged in one set of locking slots. The unidirectional movement component can restrict the movement direction of the movable block, thereby ensuring that the movable block can only move towards the direction of the first counterweight block, thus ensuring that the first and second counterweight blocks can be fixed and preventing the first and second counterweight blocks from sliding.

[0008] Furthermore, the support mechanism includes two sets of mating blocks, which are hinged together. A second locking block is fixedly connected to each set of mating blocks. Several sets of hooks are provided on both the first and second counterweight blocks, and the two sets of second locking blocks are respectively engaged within the two sets of hooks. Connecting sleeves are engaged on both sets of mating blocks. The support mechanism can support the first and second counterweight blocks, thereby fixing them in place when the tower crane sways, providing rigid fixation and ensuring the safety of the tower crane during operation.

[0009] Furthermore, the connecting sleeve is provided with two sets of fixing posts, which are respectively installed inside the two sets of mating blocks. A support rod is hinged to the connecting sleeve, and a fixing plate is fixedly connected to one end of the support rod. The fixing plate is fixed to the concrete base. Through the cooperation of the support rod and the fixing plate, the first and second counterweight blocks can be supported.

[0010] Furthermore, the bottom end of the cross support frame is provided with several sets of fixing seats, and all sets of fixing seats are placed on a concrete base.

[0011] The working principle and beneficial effects of this solution are as follows:

[0012] When in use, the staff first places the cross support frame in the designated position, then adjusts the cross support frame to be horizontal. Then, the staff hoists the two sets of first counterweights and the two sets of second counterweights to the designated position in turn. Then, depending on the needs, it is determined whether a third counterweight needs to be added. At this time, the counterweight mechanism is assembled.

[0013] Then, the staff can install the support mechanism and the abutment mechanism at the same time. The support mechanism can support the first counterweight / second counterweight. When the tower crane shakes slightly, causing the cross support frame to swing, the support mechanism can abut it to ensure the stability of the tower crane. The abutment mechanism can abut the four corners of the counterweight mechanism to ensure that the first counterweight and the second counterweight do not move, thereby ensuring that the first counterweight and the second counterweight can always fix the tower crane base.

The objectives and other advantages of this invention can be realized and obtained through the following description. Attached Figure Description

[0020] The following detailed description illustrates the specific implementation method:

[0021] Example

[0022] like Figures 1 to 4As shown, an assembled tower crane base is disclosed, including a cross support frame 1. Several sets of fixed seats 5 are fixedly connected to the bottom end of the cross support frame 1, and the fixed seats 5 are located at the four ends of the cross support frame 1. The fixed seats 5 are placed on a concrete base. Several sets of reinforcing ribs 6 are provided on the cross support frame 1. A detachable counterweight mechanism is provided on the cross support frame 1. The counterweight mechanism includes two sets of first counterweight blocks 2 and two sets of second counterweight blocks 3. Both ends of the first counterweight blocks 2 and the second counterweight blocks 3 are fixedly connected to wedge blocks 4. The wedge blocks 4 are positioned differently on the first counterweight blocks 2 and the second counterweight blocks 3. Two sets of wedge blocks 4 are placed on the cross support frame 1. The wedge block 4 on the second counterweight block 3 is placed on the wedge block 4 on the first counterweight block 2. The top and bottom surfaces of the first counterweight block 2 and the second counterweight block 3 are both located in the same horizontal plane. The two sets of first counterweight blocks 2 and the two sets of second counterweight blocks 3 form a rectangle. The four endpoints of the cross support frame 1 coincide with the four vertices of the rectangle. A third counterweight block can also be placed on the first counterweight block 2 and the second counterweight block 3. Although the third counterweight block is not shown in the attached drawings, it is a rectangular concrete block used only for counterweighting, and its structure is well known to those skilled in the art. Figure 1 and Figure 2 As shown.

[0023] A supporting mechanism is provided at each of the four ends of the cross support frame 1. The supporting mechanism includes a fixed block 8, with a first fixing groove 11 on both sides of the fixed block 8. A U-shaped block 9 is fitted into each of the two sets of first fixing grooves 11. The other end of each set of U-shaped blocks 9 is fitted onto the cross support frame 1, and one end of the U-shaped block 9 is attached to one side of the reinforcing rib 6. A detachable movable block 7 is provided on the fixed block 8. A V-shaped groove 10 is provided on both the fixed block 8 and the movable block 7. One corner of the wedge block 4 is located in the V-shaped groove 10. Two sets of limiting blocks 12 are fixedly connected to the top of both the fixed block 8 and the movable block 7. An extension block 14 is fixedly connected to the bottom of the movable block 7. A limiting groove 13 is provided on the extension block 14. The limiting block 12 on the fixed block 8 is slidably fitted into the limiting groove 13. A one-way moving component is provided between the movable block 7 and the fixed block 8. Figure 3 As shown.

[0024] The unidirectional moving component includes a first locking block 16, a second fixing groove 15 formed on a movable block 7, the first locking block 16 being slidably engaged in the second fixing groove 15, a spring 17 being disposed in the second fixing groove 15, one end of the spring 17 contacting the bottom surface of the first locking block 16, and the other end contacting the bottom surface of the second fixing groove 15, the spring 17 being located between the bottom surface of the second fixing groove 15 and the first locking block 16, and several sets of locking slots 18 formed on an extension block 14, the first locking block 16 being engaged in one set of locking slots 18. Figure 3 As shown

[0025] Several sets of hooks 19 are provided on both the first counterweight 2 and the second counterweight 3. A support mechanism is provided between the two sets of hooks 19 located on the same vertical plane. The support mechanism includes two sets of mating blocks 20. One end of the two sets of mating blocks 20 is hinged to each other, and the other end of each set of mating blocks 20 is fixedly connected to a second locking block 21. The two sets of second locking blocks 21 are respectively locked into the two sets of hooks 19. A connecting sleeve 22 is locked at the hinge of the two sets of mating blocks 20. The connecting sleeve 22 is U-shaped, and a fixing post 23 is fixedly connected inside the connecting sleeve 22. Fixing holes 24 are opened in both sets of mating blocks 20, and the two sets of fixing posts 23 are respectively inserted into the two sets of fixing holes 24. A support rod 25 is hinged to the connecting sleeve 22, and a fixing plate 26 is fixedly connected to the other end of the support rod 25. The fixing plate 26 is in contact with the bottom surface. Figure 4 As shown.

[0026] In practice

[0027] In use, the staff first places the cross support frame 1 in the designated position. At this time, several sets of fixed seats 5 are in contact with the bottom surface. It is necessary to ensure that the cross support frame 1 is horizontal. Then, the staff uses hooks 19 to hoist the two sets of first counterweight blocks 2 to the designated position. Then, the staff hoists the two sets of second counterweight blocks 3 to the designated position and adjusts the positions of the first counterweight blocks 2 and the second counterweight blocks 3 so that the two sets of vertically aligned wedge blocks 4 are completely aligned. Then, it is determined whether a third counterweight block needs to be added according to the requirements to complete the assembly of the counterweight mechanism. Then, the staff can install the support mechanism and the abutment mechanism at the same time.

[0028] When installing the support mechanism, the workers first ensure that the two sets of mating blocks 20 form an obtuse angle. Then, they move the two sets of mating blocks 20 between the two sets of hooks 19. At this time, the two sets of second locking blocks 21 are aligned with the corresponding hooks 19. Then, the workers rotate the two sets of mating blocks 20 to make them parallel, and the second locking blocks 21 are locked into the corresponding hooks 19. Then, the workers align the two sets of fixing posts 23 on the connecting sleeve 22 with the fixing holes 24, and insert the fixing posts 23 into the corresponding fixing holes 24. At the same time, the connecting sleeve 22 is fitted onto the two sets of connecting sleeves 22. At this time, the connection point of the two sets of connecting sleeves 22 is completely located inside the connecting sleeve 22. At this time, the two sets of mating blocks 20 are fixed and cannot be rotated. Then, the workers rotate the support rod 25 on the connecting sleeve 22 until the fixing plate 26 contacts the concrete base. Finally, the fixing plate 26 is fixed to the concrete base. At this time, the support mechanism can support the first counterweight 2 / second counterweight 3. When the tower crane shakes slightly, causing the cross support frame 1 to swing, the support mechanism can hold it back and ensure the stability of the tower crane.

[0029] When installing the supporting mechanism, the worker first places the fixing block 8 in a suitable position, keeping the open end of the V-groove 10 facing the wedge block 4. Then, the two sets of U-shaped blocks 9 are respectively inserted into the first fixing groove 11. The worker then pulls the fixing block 8 away from the wedge block 4 until the U-shaped block 9 contacts the corresponding reinforcing rib 6. At this time, the reinforcing rib 6 supports the fixing block 8 through the U-shaped block 9, preventing the fixing block 8 from moving backward. Then, the worker installs the first locking block 16 and the spring 17 into the second fixing groove 15. Since the cooperation between the first locking block 16 and the spring 17 and the second fixing groove 15 is existing technology, the step of installing the first locking block 16 and the spring 17 into the second fixing groove 15 is well known to those skilled in the art, and there will be no situation where installation is impossible. Then, the worker moves the movable block 7 above the fixing block 8, aligning the limiting block 12 with the limiting groove 13. Then, the worker moves the movable block 7 horizontally, causing the limiting block 12 to slide and engage in the limiting groove 13. Then, the worker continues to move... The movement causes the limiting block 12 to slide on the limiting groove 13. When the inclined surface of the first locking block 16 contacts the movable block 7, the first locking block 16 moves downward through the inclined surface, causing the spring 17 to compress. When the movable block 7 moves to one of the sets of locking grooves 18 and aligns with the first locking block 16, the spring 17 converts its elastic potential energy into kinetic energy, causing the first locking block 16 to move upward, so that the first locking block 16 is locked in the locking groove 18. This process is repeated, through the first locking block 16... 6. The spring 17 cooperates with the slot 18 to ensure that the movable block 7 can only move in one direction until the movable block 7 abuts against the wedge block 4. At this time, one corner of the wedge block 4 is located in the V-groove 10. When the operator needs to continue installing the movable block 7, a one-way moving component is installed in the movable block 7. This process is repeated to hold the four corners of the counterweight mechanism together, which can prevent the first counterweight 2 / second counterweight 3 from moving during vibration, thereby ensuring that the first counterweight 2 and the second counterweight 3 are always in the designated position.

[0030] The above description is merely an embodiment of this utility model, and common knowledge such as specific structures and characteristics in the solution is not described in detail here. It should be noted that those skilled in the art can make several modifications and improvements without departing from the structure of this utility model, and these should also be considered within the protection scope of this utility model. These modifications and improvements will not affect the effectiveness of the implementation of this utility model or its practicality.
