Description

Technical Field

[0001] This utility model belongs to the field of engineering machinery technology, and in particular relates to an auxiliary tower crane balance arm installation device. Background Technology

[0002] As the construction industry develops towards greater specialization and scale, tower cranes, as key equipment in construction projects, have been widely used in various construction projects. The popularization and promotion of tower cranes have completely revolutionized the transportation mode of building materials, greatly improved the efficiency of engineering construction, effectively shortened the project construction period, and also created a safer and more reliable working environment for operators, ensuring the smooth progress of the construction process.

[0003] In the existing tower crane structural design, the counterweight boom mainly relies on long tie rods for traction and fixation. One end of the tie rod is firmly connected to the counterweight boom, while the other end is fixed to the tower top, thus ensuring the stability of the counterweight boom during operation. However, in actual counterweight boom installation operations, the installation of long tie rods faces certain challenges. The long tie rod itself has a certain weight, and when it is under tension, it tends to retract automatically. This characteristic makes it difficult to accurately fix both ends of the long tie rod simultaneously during installation, thus creating a significant obstacle to the counterweight boom installation work and increasing the difficulty and time cost of installation. Utility Model Content

[0004] To address the technical problems mentioned in the background section, an auxiliary tower crane counterweight boom installation device is provided to solve the problem that it is difficult to fix both ends of the long tie rod above the counterweight boom of existing tower cranes to the counterweight boom and the tower top.

[0005] To achieve the above objectives, the specific technical solution of the auxiliary tower crane counterweight boom mounting device of this utility model is as follows:

[0006] An auxiliary tower crane counterweight boom mounting device includes a fixed base; the fixed base is formed by multiple sections stacked upwards sequentially, with a mounting base firmly fixedly connected to its top; the mounting base is horizontal, and a first connector is firmly fixedly connected to one end of the mounting base; the first connector is tightly connected to two sets of second connectors through a specific connection method, and the second connectors are firmly fixedly connected to one end of the counterweight boom, with a counterweight plate fixedly installed at the other end of the counterweight boom; above the counterweight boom, two sets of fixed supports are symmetrically fixedly connected, each set of fixed supports... All components are rotatably connected to the connector via a rotating joint. The connector is then reliably fixed to the long tie rod. The other end of the long tie rod is also fixedly connected to another set of connectors, which are also fixedly connected to another set of fixed supports. These fixed supports are securely fixed to one side of the sliding block. A sliding connection is formed between the sliding block and the sliding rod. The sliding rod is vertically oriented and its bottom is securely fixed to the mounting base. The side of the sliding rod away from the long tie rod supports a support frame. The support frame is fixedly connected to the sliding rod and the mounting base using high-strength bolts.

[0007] Furthermore, the first connector is composed of a connecting side plate and a rotating shaft, and a clearance groove is carefully opened on the rotating shaft; the second connector has an annular groove, and a storage groove and a slot are respectively opened on both sides of the annular groove; the second connector is provided with a buckle, one end of which is rotatably connected to one side of the annular groove by a pin shaft, and the other end can be accurately inserted into the slot.

[0008] Furthermore, a protective net is provided at the top of the balance arm; protective fences are installed on both sides above the balance arm.

[0009] Furthermore, a fixed tripod is fixedly connected to one end of the fixed base near the balance arm, and the two right-angled sides of the fixed tripod are firmly fixed to the top of the fixed base and one end of the balance arm, respectively.

[0010] Furthermore, a rotating support rod is provided at the top of the sliding rod, and a take-up rod is rotatably connected to the rotating support rod through rotating connecting components such as bearings; one end of the take-up rod is fixedly connected to the output end of the take-up motor by a key connection, and the take-up motor is securely fixed on the sliding rod; a lifting rope is wrapped around the take-up rod, and one end of the lifting rope is tied to the sliding block with a special rope buckle.

[0011] Furthermore, the sliding rod is provided with a stop block, and the sliding block has a movable groove; the stop block is precisely engaged in the movable groove, and the stop block has a horizontal pin hole, into which a limit pin is inserted, and the limit pin also passes through the sliding block.

[0012] The auxiliary tower crane counterweight boom mounting device of this utility model has the following advantages:

[0013] This invention connects one end of a long pull rod to a balance arm via a connector and a fixed support, and the other end to a sliding block via a connector and a fixed support. The sliding block is pulled upward along the sliding rod by a winding motor and a hanging rope, which in turn pulls the balance arm, causing the second connector at one end of the balance arm to rotate around the first connector until the balance arm is horizontal to the ground. The long pull rod remains taut throughout, and the balance arm is fixed by pulling it, thus avoiding the difficulty of fixing both ends of the long pull rod when it is taut.

[0024] This utility model provides an auxiliary tower crane counterweight boom mounting device, which includes a fixed base 1. The fixed base 1 is formed by multiple sections stacked upwards sequentially, and a mounting base plate 2 is firmly fixedly connected to its top. The mounting base plate 2 is horizontal, and a first connecting member 3 is firmly fixedly connected to one end of the mounting base plate 2. The first connecting member 3 is tightly connected to two sets of second connecting members 4 through a specific connection method, and the second connecting members 4 are firmly fixedly connected to one end of the counterweight boom 5. A counterweight plate 8 is fixedly installed at the other end of the counterweight boom 5. Above the counterweight boom 5, two sets of fixed supports 9 are symmetrically fixedly connected, and each set of fixed supports 9 is rotated... The auxiliary connector 10 is rotatably connected to the connector 10, which is in turn reliably fixed to the long tie rod 11. The other end of the long tie rod 11 is also fixedly connected to another set of connectors 10, which is fixedly connected to another set of fixed supports 9. These fixed supports 9 are firmly fixed to one side of the sliding block 12. The sliding block 12 and the sliding rod 13 form a sliding connection. The sliding rod 13 is set vertically, and its bottom is firmly fixed to the mounting base plate 2. The side of the sliding rod 13 away from the long tie rod 11 supports the support frame 14. The support frame 14 is fixedly connected to the sliding rod 13 and the mounting base plate 2 by high-strength bolts.

[0025] Among them, such as Figure 2As shown, the first connector 3 is composed of a connecting side plate 301 and a rotating shaft 302, and a clearance groove 3021 is carefully opened on the rotating shaft 302; the second connector 4 has an annular groove 401, and a storage groove 4011 and a slot 4012 are respectively opened on both sides of the annular groove 401; the second connector 4 is provided with a buckle 402, one end of the buckle 402 is rotatably connected to one side of the annular groove 401 by a pin, and the other end can be accurately inserted into the slot 4012; during installation, the rotating shaft 302 is inserted into the annular groove 401, and after insertion, the buckle 402 passes through the clearance groove 3021 and is inserted into the slot 4012, and the buckle 402 acts as a limit stop to limit the rotating shaft 302, so that the second connector 4 and the balance arm 5 can rotate around the first connector 3.

[0026] Among them, such as Figure 1 As shown, a protective net 6 is installed at the top of the balance arm 5; protective railings 7 are installed on both sides above the balance arm 5; when workers check the connection status of the two ends of the long tie rod 11 on the balance beam 5 or check whether there are cracks on the long tie rod 11, safety protection is provided to prevent workers from falling from height.

[0027] Among them, such as Figure 5 As shown, a fixed tripod 20 is fixedly connected to one end of the fixed base 1 and the balance arm 5. The two right-angled sides of the fixed tripod 20 are firmly fixed to the top of the fixed base 1 and one end of the balance arm 5, respectively. By utilizing the stability principle of triangles, the stability of the connection between the fixed base and the balance arm is enhanced.

[0028] Among them, such as Figure 6 As shown, a rotating support rod 15 is provided at the top of the sliding rod 13, and a take-up rod 16 is rotatably connected to the rotating support rod 15 through rotating connecting components such as bearings; one end of the take-up rod 16 is fixedly connected to the output end of the take-up motor 17 by a key connection, and the take-up motor 17 is firmly fixedly installed on the sliding rod 13; a lifting rope 18 is wrapped around the take-up rod 16, and one end of the lifting rope 18 is tied to the sliding block 12 with a special rope buckle. The rotation of the take-up motor 17 tightens the lifting rope 18, thereby controlling the lifting of the sliding block 12.

The stop 1301 is precisely engaged in the movable groove 1201. A horizontal pin hole is provided on the stop 1301, and a limit pin 19 is inserted into the pin hole. The limit pin 19 also passes through the sliding block 12, thereby limiting the movement range of the sliding block 12 on the sliding rod 13, and fixing the sliding block 12 at a specific height position on the sliding rod 13 by the limit pin 19.

[0030] The specific usage and function of this embodiment are as follows:

[0031] In this utility model, the balance arm 5 is hoisted onto the fixed base 1 by an engineering vehicle, so that the rotating shaft 302 of the first connecting member 3 fixed at one end of the mounting base 2 is inserted into the annular groove 401 of the second connecting member 4 fixed at one end of the balance arm 5. After being inserted, the buckle 402 passes through the clearance groove 3021 and is inserted into the slot 4012. The buckle 402 acts as a limiting stop to limit the rotating shaft 302, so that the second connecting member 4 and the balance arm 5 can rotate around the first connecting member 3, and the balance arm 5 tilts downward as a whole. The connector 10 located at the upper end of the long tie rod 11 is connected to the fixed support 9 on one side of the sliding block 12. The rotation of the take-up motor 17 tightens the rope 18 around the take-up lever 16, thereby controlling the sliding block 12 to rise. The long pull rod 11 pulls the balance arm 5 to rotate until it reaches a horizontal position. At this time, the stop block 1301 is inserted into the movable groove 1201, and the sliding block 12 is fixed at the height position of the sliding rod 13 by the limit pin 19. The fixed tripod 20 is installed so that the two right-angled sides of the fixed tripod 20 are firmly fixed to the top of the fixed base 1 and one end of the balance arm 5, respectively. The stability principle of the triangle is used to enhance the stability of the connection between the fixed base and the balance arm.

[0032] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model.
