The construction period is quite tight, and generally tower belt machines, top belt machines, mobile feeders and other equipment are used for lifting and pouring.

[0003] The tower belt machine is a combination of a tower crane and a feeder or a feeder pipe, and the pouring position, angle and length of the feeder belt or the feeder pipe are changed by the tower crane. The total length of the feeder belt reaches 100m, and is used to deliver concrete to the pouring position, so higher requirements are put forward for the lifting capacity and stability of the tower crane. For a general tower crane, such as the anti-collision novel tower crane disclosed in CN218754710U, a support frame needs to be arranged on the rotary table and connected with the lifting arm and the counterweight arm through a pull rod. However, for the tower belt machine, the length of the feeder is large and the weight is heavy, so higher requirements are put forward for the stability of the tower body. Therefore, the support frame on the rotary table needs to be optimized. At the same time, with the pouring of concrete, the pouring working surface is continuously raised, and the lifting arm of the tower belt machine also needs to be raised synchronously. Therefore, a support frame installed on the rotary platform of the tower pouring equipment is proposed. SUMMARY

DETAILED DESCRIPTION

[0025] The embodiments of the utility model will be described in detail below, the examples of the embodiments are shown in the drawings, the embodiments described below by referring to the drawings are exemplary, and are intended to explain the utility model, and can not be understood as the limitation of the utility model.

[0026] Embodiment 1:

[0027] As shown in Figs. 1-3 A support frame mounted on the rotary platform of tower pouring equipment includes first frame body 1 and second frame body 2, the height of first frame body 1 and second frame body 2 is consistent, two groups of connecting inclined rods 3 are arranged on the top of second frame body 2, the upper end of two groups of connecting inclined rods 3 is connected with first pull rod plate 4, and the lower end is connected with the two sides of second frame body 2; two groups of second pull rod plates 5 are arranged on the top of first frame body 1, and second pull rod plates 5 are connected with first pull rod plate 4 through top connecting rod 6, specifically, two groups of top connecting rod 6 are arranged, the upper end is hinged with first pull rod plate 4, and the lower end is connected with corresponding second pull rod plate 5.

[0028] Two sets of track beams 7 are provided between the first frame 1 and the second frame 2. The track beams 7 are used to install the lifting trolley.

[0029] Both sets of track beams 7 are equipped with mounting frames 8 on their outer sides. The mounting frames 8 are used to install the jacking mechanism. The mounting frames 8 are located above the tower body of the tower conveyor. The jacking mechanism is a jacking hydraulic cylinder or a jacking electric cylinder, etc.

[0030] Both the first tie rod plate 5 and the second tie rod plate 4 are provided with pin holes 14 for connecting with the tower belt conveyor tie rod.

[0031] Preferably, the mounting bracket 8 is provided with a plurality of mounting holes 802 for fixing the lifting mechanism. Specifically, the tail end of the lifting mechanism is provided with a connecting ear plate, which is connected by a plug-in hydraulic cylinder or a pin. Multiple sets of mounting holes 802 are provided, allowing the lifting mechanism to be installed in mounting holes 802 at different heights, thus adjusting the installation height of the lifting mechanism.

[0032] Preferred, such as Fig. 2 and 3 As shown, both the first frame 1 and the second frame 2 include two sets of vertical rods 11, with several connecting horizontal rods 12 between the vertical rods 11, and diagonal connecting rods 13 between adjacent connecting horizontal rods 12.

[0033] The lower ends of the first frame 1 and the second frame 2 are provided with through-pin ear plates 15 for hinged connection with the mounting base on the slewing platform. After the first frame 1 and the second frame are hoisted onto the slewing platform of the tower belt conveyor, the through-pin ear plates 15 are connected to the mounting base by pins for easy installation.

[0034] In practical use, the first tie rod plate 4 is connected to the lifting arm via a tie rod, and the second tie rod plate 5 is connected to the counterweight arm via a tie rod. This design can effectively distribute the load transmitted from the lifting arm and counterweight arm of the tower belt conveyor, improve the support stability of the lifting arm and counterweight arm, ensure that the tower belt conveyor operates more smoothly and safely during hoisting and material placement, and reduce the safety risks caused by unstable support.

[0035] When it is necessary to increase the height of the tower, the increased tower section is first hoisted to the top of the tower section using a crane trolley set on the track beam 7. The two tower sections are then connected, and a jacking operation is carried out. The slewing platform, the boom, and the counterweight boom are simultaneously lifted upwards. Specifically, after the tower section is increased in height, the jacking mechanism pushes it downwards, supporting the top of the newly added tower section. Then, the locking of the slewing platform is released, and the jacking mechanism continues to extend, raising the entire slewing platform and locking it onto the increased tower section. This completes the adjustment of the boom height, enabling the tower conveyor to continuously meet the pouring requirements at different heights, ensuring the continuity and efficiency of construction.

[0036] Example 2:

[0037] Unlike Embodiment 1, the mounting frame 8 is connected to the second frame 2 via several connecting rods 9, specifically, adjacent connecting rods 9 are connected in a figure-eight pattern. This connection method enhances the connection strength and stability between the mounting frame 8 and the second frame 2, making the entire support frame structure more robust and reliable. Simultaneously, the first frame 1 and the mounting frame 8 are connected by diagonal braces 10, further improving the overall structural strength and deformation resistance of the support frame, ensuring stable operation even in complex construction environments.

[0038] Example 3:

[0039] Unlike Example 1, such as Fig. 2 As shown, the mounting frame 8 has an inner clearance groove 801, and the track beam 7 is disposed in the clearance groove 801.

[0040] The mounting frame 8 has an inner clearance groove 801, and the track beam 7 is set in the clearance groove 801, so as not to affect the movement of the crane trolley on the track beam 7.

[0041] The working principle of this utility model is as follows:

[0042] The first tie rod plate 5 and the second tie rod plate 4 are respectively connected to the lifting arm and the counterweight arm through tie rods. The first tie rod plate 5 and the second tie rod plate 4 are respectively set at the top of the connecting diagonal bar 3 at the top of the second frame 2 and the top of the first frame 1, effectively dispersing the load transmitted from the lifting arm and the counterweight arm of the tower belt conveyor, and improving the support stability of the lifting arm and the counterweight arm.

[0043] When it is necessary to add a tower section, the added tower section is hoisted to the top of the tower section using a crane trolley set on the track beam 7. The two tower sections are then connected, and a jacking operation is performed. The jacking mechanism pushes downwards, supporting the top of the newly added tower section. Then, the locking of the slewing platform is released, and the jacking mechanism continues to extend, raising the entire slewing platform and locking it onto the added tower section. This completes the adjustment of the boom height, enabling the tower conveyor to continuously meet the pouring requirements at different heights, ensuring the continuity and efficiency of construction.
