[0002] A tower crane is a rotating crane with a boom mounted on the top of a tall tower. It has a large operating space and is mainly used for vertical and horizontal transportation of materials and installation of building components in housing construction. The whole crane is mainly composed of three parts: metal structure, working mechanism and electrical system. The metal structure includes the tower body, boom and base foundation, etc. The working mechanism has four parts: lifting, luffing, rotation and travel. The electrical system includes motors, controllers, distribution cabinets, connecting lines, signals and lighting devices, etc.

[0003] The bottom foundation is the bearing part of the entire tower crane, and its own stability determines the overall operating stability of the tower crane. The common tower crane bottom foundation adopts a pile-barrel structure, in which the pile barrel is buried deep in the soil layer. However, in the silt soil construction environment, after the traditional pile barrel with a relatively smooth outer wall penetrates into the soil layer, its horizontal and vertical reinforcement methods rely closely on friction, and the overall anti-subsidence effect is not good.

DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0026] In addition, the terms used below are defined based on the functions of the present invention and may differ depending on the intention or custom of the user or operator. Therefore, these terms are defined based on the entire contents of this specification.

[0027] See also Figure 1-4 The utility model discloses a silt soil layer tower crane foundation, comprising a tower crane body 1, a foundation plate 2 and a reinforcement member 3. The bottoms of the four vertical rods of the tower crane body 1 are welded with connecting plates, the lower end surface of the connecting plates is a horizontal surface, and each connecting plate is equipped with a connecting bolt;

[0028] The base plate 2 is a steel structure material component. The overall strength of the connecting plate base plate 2 is not easy to deform. The base plate 2 is connected to the connecting plate through the connecting bolts. The overall verticality of the tower crane body 1 is ensured by leveling the base plate 2. The base plate 2 has through holes at equal angles in the circumferential direction.

[0029] The reinforcement member 3 is centrally located just below each through hole, and includes a reinforcement shell 31 fixed to the lower end surface of the base plate 2 by high-strength bolts. The lower end surface of the reinforcement shell 31 can vertically penetrate into the soil layer, and the stability of the base plate 2 and the tower crane body 1 is reinforced by the reinforcement shell 31. The outer wall of the reinforcement shell 31 can be frosted to increase the friction between the reinforcement shell 31 and the soil layer.

[0030] like Figure 1-Figure 4 As shown, an axis frame 32 is provided at the upper position of the inner wall of the reinforcement shell 31, and a screw rod 33 is rotatably installed at the center position of the axis frame 32. The top of the screw rod 33 passes through the through hole and extends to the top of the base plate 2. A screw rod sleeve 34 is installed on the outer side of the screw rod 33. The outer wall of the screw rod sleeve 34 is symmetrically welded with a limiting rod 35. The inner wall of the reinforcement shell 31 is symmetrically provided with a limiting groove 36, and the limiting rod 35 is located in the limiting groove 36. Through holes 37 are symmetrically provided in the lateral position of the reinforcement shell 31. A positioning frame 38 is installed at the lower position of the inner side of the reinforcement shell 31. The outer wall of the positioning frame 38 is symmetrically welded with positioning rods. The outer wall of the positioning rod is sleeved with a reinforcement rod 39, and a part of the reinforcement rod 39 is inserted in the through hole 37. In the initial state, the end face of the reinforcement rod 39 is flush with the outer wall of the reinforcement shell 31.

[0031] A driving arm 30 is hinged between the reinforcement rod 39 and the limiting rod 35. A rotating handwheel 331 is fixedly installed on the top of the screw rod 33, and the outer wall of the rotating handwheel 331 is provided with anti-skid patterns. During operation, when the reinforcement shell 31 is deeply embedded in the soil layer, the operator rotates the rotating handwheel 331 to drive the screw rod 33 to rotate in the shaft frame 32. The anti-skid patterns provided on the outer wall of the rotating handwheel 331 can increase its surface friction. Since the limiting groove 36 locks the circumferential rotation direction position of the limiting rod 35, after the screw rod 33 rotates and engages with the thread of the screw sleeve 34, the screw sleeve 34 and the limiting rod 35 can move vertically downward relative to the outer wall of the screw rod 33, and the limiting rod 35 As the distance between the driving arm 30 and the reinforcing rod 39 decreases, the limiting rod 35 applies a thrust to the driving arm 30, the angle between the driving arm 30 and the reinforcing rod 39 decreases, and the end of the driving arm 30 connected to the reinforcing rod 39 applies a horizontal thrust to it. Under the action of the horizontal thrust, the reinforcing rods 39 at each position expand horizontally outward along the through hole 37 and penetrate into the soil layer laterally, so that the longitudinal position of the reinforced shell 31 can be reinforced. Under the action of the reinforcing rods 39, the tower crane body 1 can be effectively prevented from sinking. There are multiple reinforcement rods 39, and the multiple reinforcement rods 39 can be distributed at equal angles in the circumferential direction of the same horizontal plane or distributed at equal intervals in the vertical direction to increase the overall stability of the entire tower crane body 1.

[0032] In another embodiment, see Figure 1-Figure 4A deflection plate 393 is hinged in the internal cavity of the reinforcement rod 39, and a first vertical hole 391 and a second vertical hole 392 are respectively opened in the top of the internal cavity of the reinforcement rod 39. An annular rod 301 is fixedly installed on the side wall of the driving arm 30, and the annular rod 301 and the bottom hinge of the driving arm 30 are cocentric. One end of the annular rod 301 passes through the first vertical hole 391 and can be slidably installed on the bottom of the deflection plate 393, that is, one end of the annular rod 301 is in the internal cavity of the reinforcement rod 39, and the outer wall of the annular rod 301 does not contact the inner wall of the internal cavity of the reinforcement rod 39. An outer convex rod 394 is provided on the top of the deflection plate 393. During specific operation, when the angle between the driving arm 30 and the reinforcement rod 39 is reduced, the driving arm 30 synchronously drives the annular rod 301 to move, and the movement form is to rotate with the center of the bottom hinge of the driving arm 30 as the center of the circle. After the annular rod 301 rotates, the bottom is relatively deflected The bottom of the plate 393 slides and applies a thrust to the bottom of the deflection plate 393, so that the deflection plate 393 deflects under the thrust. This process is performed synchronously with the outward expansion process of the reinforcement rod 39. In the first half of the process (i.e., when the second vertical hole 392 moves from the inside of the reinforcement shell 31 to its outside), the deflection plate 393 drives the outer protruding rod 394 to move toward the second vertical hole 392, and the top horizontal height of the outer protruding rod 394 is lower than the horizontal height of the upper end surface of the second vertical hole 392. In the second half of the process (i.e., after the second vertical hole 392 moves to the outside of the reinforcement shell 31, the reinforcement rod 39 continues to move horizontally), the deflection plate 393 continues to drive the outer protruding rod 394 to deflect, drive the outer protruding rod 394 to leak out of the second vertical hole 392, and the top of the outer protruding rod 394 is inserted into the soil layer. The lateral position is reinforced by the outer protruding rod 394, thereby further increasing the overall stability of the tower crane body 1.

[0033] See also Figure 4 The outer wall of the reinforcement rod 39 is sleeved with a supporting outer sleeve 41, and a supporting rod 42 is welded to the bottom of the supporting outer sleeve 41. The bottom of the supporting rod 42 is fixedly connected to the inner wall of the reinforcement outer shell 31. When the reinforcement rod 39 moves, it slides along the inner wall of the supporting outer sleeve 41, and the outer wall of the reinforcement rod 39 is supported by the supporting outer sleeve 41 to prevent the positioning frame 38 from being deformed.

[0034] See also Figure 1-Figure 4 One of the end faces of the reinforcement shell 31, the reinforcement rod 39 and the external convex rod 394 is a conical surface, which is the contact surface with the soil layer, reducing the contact area between the reinforcement shell 31, the reinforcement rod 39 and the external convex rod 394 and the soil layer, making it easier for the reinforcement shell 31, the reinforcement rod 39 and the external convex rod 394 to enter the soil layer.

[0035] See also Figure 2-Figure 3The interior of the reinforced shell 31 is provided with reinforcing rods 51 in the horizontal direction. There are multiple reinforcing rods 51 which are arranged parallel to each other. The reinforcing rods 51 increase the supporting force of the inner wall of the reinforced shell 31 to prevent the reinforced shell 31 from being concave and deformed.

[0036] See also Figure 2-Figure 4 A shaft seat 52 is installed at the center of the bottom of the reinforced shell 31, and the bottom of the screw rod 33 is installed in the shaft seat 52. When the screw rod 33 rotates, its bottom rotates in the shaft seat 52, thereby increasing the stability of the screw rod 33 when rotating.

[0037] See also Figure 2-Figure 4 A ball is provided at the connection between the limit rod 35 and the limit groove 36, and the ball is embedded in the two side walls of the limit rod 35. When the limit rod 35 vertically descends along the limit groove 36, the ball will roll on the inner wall of the limit groove 36, and the relative friction between the two is smaller.
