Description

Technical Field

[0001] The utility model relates to the technical field of tower crane equipment, in particular to a safety device for placing counterweights in a classified manner for a tower crane. Background Art

[0002] The tower crane counterweight is a device that adds appropriate weights to the equipment during construction to keep the tower crane balanced and stable at all times, avoiding tilting, crookedness, and shaking during construction, thereby ensuring construction safety and normal operation.

[0003] The importance of the tower crane counterweight is self-evident. If there is no correct counterweight, the tower crane structure will tilt, the top of the tower crane will shake, the boom will bend, and other problems will easily occur, which will not only lead to low construction efficiency, but also increase safety hazards. Therefore, before construction, it is necessary to fully calculate the counterweight and select the appropriate counterweight coefficient and counterweight scheme. The factors affecting the tower crane counterweight include the height, arm length, lifting weight, working radius, etc. of the tower crane. Different factors will affect the size and form of the counterweight. When calculating the counterweight, these factors need to be considered and adjusted according to the actual situation.

[0004] The remaining counterweights of the tower crane will lie flat on the counterweight wall when not in use. However, the counterweights will squeeze each other when stacked. During the process of hoisting and taking the counterweights, since the counterweights are also in a vertical state in the counterweight state, the counterweights are generally lifted vertically. At the same time, lifting in this state will cause the counterweights to be damaged, causing the coating on the surface of the counterweights to fall off, which in turn makes the counterweights susceptible to corrosion. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a tower crane counterweight classification placement safety device to solve the problem that when the counterweight is not in use, the counterweight is placed flat on the counterweight wall. The counterweight in the flat state is troublesome to hoist, and it will also cause the counterweights to collide with each other, causing damage to the counterweight, which in turn affects the weight imbalance of the counterweight.

[0006] In order to solve the above problems, the technical solution adopted by the utility model is:

[0007] A safety device for the classified placement of counterweights for a tower crane comprises a counterweight beam for clamping the tower crane counterweight, wherein the counterweight beam is arranged on both sides of the tower crane counterweight, and the surface of the counterweight beam is evenly provided with clamping grooves for clamping the counterweights on both sides, and the bottom surfaces of both ends of the counterweight beam are connected with horizontal main pole beams, which support the counterweight beam, and the bottom end of the main pole beam is vertically fixed with a column connected to the ground.

[0008] The principle of this scheme is:

[0009] The protrusions on both sides of the counterweight are placed and snapped into the slots of the counterweight beam. Since the slots are evenly arranged on the counterweight beam, the slots at corresponding positions can be selected according to the mass and size of the counterweight to clamp and limit the counterweight; the main beam is supported on the ground to complete the vertical storage of the counterweight.

[0010] The beneficial effects of this program are:

[0011] In the present application, slots are evenly arranged on the surface of the counterweight beam, so that the slots at corresponding positions can be selected to store the counterweights according to the size and quantity of the counterweights. At the same time, the spacing between adjacent counterweights can also be adjusted to ensure that when the counterweights are stored, collisions between adjacent counterweights are avoided to avoid damage to the counterweights. Secondly, the counterweights are placed perpendicular to the ground. When hoisting, the counterweights can be lifted vertically, making lifting more convenient.

[0012] Furthermore, the counterweight beam includes a first counterweight rod and a second counterweight rod, a limit rod is cross-connected between the first counterweight rod and the second counterweight rod, and the bottom of the limit rod is slidably connected to the first counterweight rod and the second counterweight rod respectively through a second slide groove; the counterweight is placed between the first counterweight rod and the second counterweight rod, so that the counterweight can be limited and clamped to avoid lateral deviation of the counterweight. At the same time, the limit rod is connected using the second slide groove. When the number of counterweights is small, the limit rod moves horizontally on the counterweight beam to block the counterweights at the ends and clamp the counterweights at the ends to avoid the counterweights accidentally escaping from the slots and causing safety hazards.

[0013] Furthermore, the ends of both ends of the counterweight beam are respectively provided with first blocks protruding upwards, and the use of the first blocks can limit the moving position of the second slide groove to prevent the limit rod from detaching from the counterweight beam when the limit rod is moved.

[0014] Furthermore, a pad is placed between the first counterweight rod and the main beam, and the bottom end of the pad is fixedly welded to the main beam. The pad supports the first counterweight rod. The pad is used to allow the first counterweight rod and the second counterweight rod to be on the same horizontal line, ensuring that the balance weight is in a horizontal position when placed, and avoiding the horizontal weight from tilting.

[0015] Furthermore, a first slide groove is slidably connected between the second counterweight rod and the main beam. The first slide groove is stuck on the surface of the main beam. The bottom depth of the first slide groove is consistent with the height of the pad, so that the first counterweight rod and the second counterweight rod are on the same horizontal line. When placing a smaller balancing weight, you only need to push the second counterweight rod toward the first counterweight rod. After the first counterweight rod is moved, screw the bolt into the first slide groove to fix the first slide groove.

[0016] Furthermore, a second stopper protruding upward is provided at one side end of the main beam. The purpose of providing the second stopper is to prevent the first slide groove from detaching from the main beam when the first slide groove slides, causing the second counterweight rod to fall to the ground, thereby damaging the second counterweight rod and avoiding safety hazards.

DETAILED DESCRIPTION

[0024] The following is further described in detail through specific implementation methods:

[0025] Attach Figure 1 For example, in the attached figure, the main beam 4 is arranged horizontally, the first counterweight rod 2-1 and the second counterweight rod 2-2 are arranged longitudinally, and the first stopper 9 is respectively arranged at the front and rear ends of the first counterweight rod 2-1 and the second counterweight rod 2-2, which is used as the direction reference.

[0026] The embodiment is basically as shown in the attached Figure 1 As shown:

[0027] The counterweight 10 of the tower crane is a device to ensure the normal operation of the tower crane during construction. The counterweight 10 of the tower crane is as shown in the attached Figure 2 As shown, the left and right sides of the counterweight 10 protrude outwards. When part of the counterweight 10 is not in use, the counterweight 10 needs to be neatly placed to avoid potential safety hazards.

[0028] As attached Figure 1 To Attachment Figure 5 As shown, four vertical columns 5 are fixedly connected on the ground, and the tops of two adjacent columns 5 are fixedly connected with a transverse main beam 4. Figure 1 and attached Figure 2 As shown, a second stopper 4-1 protruding upward is provided on the right side of the two main beams 4, a counterweight beam 2 is longitudinally installed between the two main beams 4, and the counterweight beam 2 is symmetrically divided into a first counterweight rod 2-1 and a second counterweight rod 2-2 along the middle of the main beam 4. The top surface of the counterweight beam 2 is evenly provided with slots 2-3 for the side protrusions of the counterweight 10 to snap into; the slots 2-3 at the corresponding position are selected according to the specifications of the counterweight 10 for snapping into, thereby adjusting the distance between adjacent counterweights 10 to achieve the limitation of counterweights 10 of different sizes.

[0029] A pad 8 is placed between the first counterweight rod 2-1 and the main beam 4, and the bottom end of the pad 8 is fixedly welded to the top surface of the main beam 4. At the same time, a first slide groove 3 that can slide laterally is placed between the second counterweight rod 2-2 and the main beam 4. The thickness of the pad 8 is consistent with the bottom wall thickness of the first slide groove 3, so that the first counterweight rod 2-1 and the second counterweight rod 2-2 are in the same horizontal plane, thereby ensuring that the balancing weight 10 is in a horizontal state when placed, avoiding the balancing weight 10 from being skewed and causing safety hazards.

[0030] The first slide slot 3 can be adjusted according to the size of the counterweight 10. If the size of the counterweight 10 is too small, the bolts fixing the first slide slot 3 are loosened, and the strip holes are used to cooperate between the first slide slot 3 and the bolts. Then the second counterweight rod 2-2 box is pushed to move toward the first counterweight rod 2-1. After the second counterweight rod 2-2 moves to the specified position, the first slide slot 3 and the main beam 4 are fixed with bolts to prevent the second counterweight rod 2-2 from being displaced. At the same time, the second stopper 4-1 set on the right side of the main beam 4 can limit the moving distance of the first slide slot 3 to prevent the second counterweight rod 2-2 from sliding from the main beam 4 to the ground, which may easily cause damage to the main beam 4 and also create safety hazards.

[0031] A limit rod 7 is installed horizontally on the top of the two longitudinally arranged counterweight beams 2. The bottom surfaces of both ends of the limit rod 7 are connected with the second slide groove 1 by bolts. At the same time, evenly distributed threaded holes for connecting the second slide groove 1 are opened on the counterweight beam 2. The threaded holes are not drawn in the accompanying drawings. The second slide groove 1 is slidably connected with the first counterweight rod 2-1 and the second counterweight rod 2-2; when the number of balancing weights 10 placed on the counterweight beam 2 is relatively small, the limit rod 7 is moved longitudinally at this time, one side of the limit rod 7 is brought close to the adjacent balancing weight 10, and the bolts are screwed into the threaded holes on the surface of the counterweight beam 2 to fix the limit rod 7, so as to prevent the balancing weight 10 from accidentally slipping out of the slot 2-3 and causing a safety hazard.

[0032] The front and rear ends of the counterweight beam 2 are respectively provided with first stoppers 9 protruding upwards, and the first stoppers 9 can limit the sliding distance of the limiting rod 7 to prevent the limiting rod 7 from sliding off the counterweight beam 2.

[0033] The specific implementation process is as follows:

[0034] According to the size of the counterweight 10, loosen the bolts fixing the first slide slot and push the second counterweight rod 2-2 to move; after the second counterweight rod 2-2 moves to the specified position, tighten the bolts fixing the first slide slot 3 and then hoist the counterweight 10 in turn and place it on the slot 2-3 of the counterweight beam 2; finally, move the limit rod 7, move the limit rod 7 to the side of the counterweight 10, and use bolts to fix the second slide slot 1 to complete the placement of the counterweight 10.

[0035] The above is only an embodiment of the utility model, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the utility model, 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.
