Description

Technical Field

[0001] The utility model relates to the technical field of tensioning trolleys, in particular to a novel remote-controlled transversely movable tensioning trolley. Background Art

[0002] During the construction process of continuous beams or continuous rigid frame bridges, transverse prestressing and longitudinal prestressing are required. When performing transverse prestressing, the tensioning position is at the two ends of the transverse bridge of the bridge. The tensioning construction requires the installation of jacks on the transverse end face steel strands of the bridge. During the precast beam prestressing construction, the jacks and tensioning pump stations used are relatively heavy, especially for railway prestressing, which often uses large-tonnage jacks. The existing construction method is to set up a tensioning trolley at the current tensioning position, install an electric hoist on the tensioning table, and lift the large-tonnage jack by the electric hoist. Then, the jack is manually installed in place. Due to the different heights of the operating positions, an operating table will be set up on the tensioning table, and workers will operate on the operating table.

[0003] However, since the position of the operating table is fixed and the edge of the tensioning trolley is some distance away from the beam body, the operator will lean forward to operate, which is very inconvenient. The present technical solution is now proposed for improvement. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art that the operating platform of the tensioning trolley cannot provide a better standing space when in use and has certain dangers, and to provide a new remote-controlled transverse-moving tensioning trolley.

[0005] In order to achieve the above-mentioned purpose, the embodiment of the present utility model specifically adopts the following technical solutions: a new remote-controlled transverse-moving tensioning trolley, comprising a mobile chassis, a remote control module is arranged inside the mobile chassis, a lifting structure is arranged above the mobile chassis, a working part is arranged on the upper surface of the mobile chassis, the working part comprises an equipment slot arranged on the mobile chassis, a slide that moves along the width direction of the mobile chassis is arranged inside the equipment slot, and a lifting platform is arranged inside the slide.

[0006] Furthermore, the hoisting structure includes two fixed beams arranged along the length direction of the mobile chassis, a hoist beam is arranged on the fixed beam, and an electric hoist is arranged on the hoist beam.

[0007] Furthermore, the equipment slot is open at one end toward the working surface, and two first screw rods for driving the slide are provided inside the equipment slot, and a base for cooperating with the first screw rods is provided at the bottom of the slide.

[0008] Furthermore, two guide rails are provided on the outer sides of the two first screw rods, and the guide rails are arranged parallel to the first screw rods. A slider is provided at the bottom of the slide and is slidably connected to the guide rails.

[0009] Furthermore, the guide rail and the first screw rod both protrude from the equipment slot.

[0010] Furthermore, the lifting platform is a scissor-type lifting platform, and the upper part of the slide is provided with four second screw rods respectively connected to the scissor-type frame at the bottom of the lifting platform. A mounting seat is provided in the middle position of the slide, and one end of the second screw rod is rotatably connected to the mounting seat.

[0011] The beneficial effects of the embodiment of the utility model are as follows: a slide that can move along the width direction of the mobile chassis is provided inside the equipment slot. The design of the slide allows the operator to perform operations in different positions. Small-range movement does not require moving the entire trolley. The first screw can push the slide outward, which can make the internal lifting platform closer to the beam body. When installing the jack, the operator can exert force better, which improves the convenience of the operator and greatly improves the efficiency and safety of tensioning operations in construction.

[0016] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0017] See also Figures 1 to 3 The embodiment of the utility model discloses a new remote-controlled transverse-moving tensioning trolley, which mainly includes a mobile chassis 1, a lifting structure and a working part. The mobile chassis 1 serves as the basis of the entire trolley, and a remote control module is integrated inside. Wheels are installed at the bottom. When in use, the entire trolley can be moved by remote control. The remote control module has been disclosed in the prior art and the applicant will not elaborate on it again.

[0018] A lifting structure is provided above the mobile chassis 1 for lifting and moving heavy objects, such as a jack. The lifting structure includes two fixed beams 101 arranged along the length direction of the mobile chassis 1. A hoist beam 102 is installed on the fixed beam 101. The hoist beam 102 is connected to the fixed beam 101 by installing wheels, so that the hoist beam 102 can slide along the fixed beam 101. An electric hoist 103 is provided on the hoist beam 102. The electric hoist 103 can be used to easily lift and move heavy objects, thereby facilitating subsequent tensioning operations.

[0019] The working part includes an equipment slot 2 arranged on the mobile chassis 1. The equipment slot 2 is open to the side of the beam body. A slide 3 that can move along the width direction of the mobile chassis 1 is provided inside the equipment slot 2. The position of the opening is convenient for the slide 3 to slide out, and the design of the slide 3 allows the operator to perform operations at different positions. Small-range movement does not require moving the entire trolley. A lifting platform 4 is also provided inside the slide 3. For high-altitude work points, the operator can stand on the lifting platform 4 to operate. The height can be adjusted as needed to adapt to tensioning operations at different heights. It is easy to adjust and simple to use.

[0020] In order to realize the movement of the slide 3, two first screw rods 201 are set inside the equipment slot 2, and two guide rails 203 parallel to the first screw rod 201 are also set on the outside of the first screw rod 201. The bottom of the slide 3 is provided with a base cooperating with the first screw rod 201 and a slider slidingly connected to the guide rail 203, so as to ensure the stability and accuracy of the slide 3 during movement, and the guide rail 203 and the first screw rod 201 both protrude from the equipment slot 2. A support plate is installed at the bottom of the guide rail 203 outside the equipment slot 2, and a bearing seat is installed at the outer end of the first screw rod 201 to ensure stability. When in use, the first screw rod 201 can push the slide 3 outward, which can make the internal lifting platform 4 closer to the beam body. When installing the jack, the operator can exert force better, which greatly ensures the safety of the operator and improves the comfort level.

[0021] The lifting platform 4 adopts the design of a scissor-type lifting platform 4, and the lifting function can be realized by the extension and contraction of the scissor-type frame. On the upper part of the slide 3, we set four second screw rods 202 that are respectively connected to the scissor-type frame at the bottom of the lifting platform 4. One end of the second screw rod 202 is rotatably connected to the mounting seat 301 in the middle of the slide 3. The mounting seat 301 is used to ensure the stability of operation. The driving motor of the second screw rod 202 is installed inside the slide 3 to increase the degree of integration. The lifting of the lifting platform 4 can be achieved by limited remote control or wireless remote control. The lifting and lowering and left and right movement of the lifting platform 4 are achieved through the mutual cooperation of the four second screw rods 202, so that the lifting platform 4 can be closer to the work point, which improves the convenience of the operator and greatly improves the efficiency and safety of the tensioning operation in construction. Whether it is transverse prestressed tensioning or longitudinal prestressed tensioning, it can provide construction personnel with a stable, efficient and safe operating platform.
