Description

Technical Field

[0001] The present application belongs to the technical field of tooling trolleys, and in particular relates to a longitudinal beam transfer trolley. Background Art

[0002] The traditional assembly method of the longitudinal beam is to assemble it at a fixed station, with multiple processes interspersed, and the assembly efficiency is low. After assembling a set of longitudinal beams, they are hoisted to the next station for track assembly. Because the longitudinal beam is heavy and there is a deviation in the weight at both ends, the hoisting position needs to be adjusted according to the center of gravity during the hoisting process, and there is a certain degree of danger in the hoisting process. In addition, due to the heavy weight of the longitudinal beam, the edges and corners on the longitudinal beam are easily cut by the slings, ring ropes, etc. during the hoisting process. The use of iron chains for hoisting is easy to damage the paint surface of the longitudinal beam. Transportation by hoisting is not only dangerous, but also easy to damage the longitudinal beam. Summary of the invention

The transmission device drives the mobile supports on both sides to move synchronously in opposite directions through the driving member. Each mobile support is symmetrically arranged with slide rails on both sides of the transmission device. The trolley chassis is provided with slideways corresponding to the slide rails, and the slide rails are slidably connected to the slideways.

The stability during the movement is ensured by symmetrically arranging the slide rails on both sides of the driving device.

[0024] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present application and its application or use. Example 1

[0025] like Figure 1 As shown, a longitudinal beam transfer trolley includes a trolley chassis 2, a mobile support 1, a transmission device 3 and a driving member 4. The mobile support 1 is slidably connected on both sides of the trolley chassis 2. The transmission device 3 drives the mobile supports 1 on both sides to move synchronously in opposite directions through the driving member 4. Each mobile support 1 is symmetrically arranged with slide rails 11 on both sides of the transmission device 3. The trolley chassis 2 is provided with a slideway 21 corresponding to the slide rail 11, and the slide rail 11 is slidably connected with the slideway 21.

[0026] The transmission device 3 drives the two side mobile supports 1 to move synchronously in the opposite direction through the driving member 4, and drives the two side mobile supports 1 to move along the slideway 21, so as to adjust the distance between the two mobile supports 1, and thus be suitable for the transportation of different types of longitudinal beams. By symmetrically arranging the slide rails 11 on both sides of the driving device, the sliding of the mobile support 1 is limited, thereby ensuring the stability during the movement. Example 2

[0027] The difference between this embodiment and embodiment 1 is that: Figure 1-Figure 4 As shown, the transmission device 3 includes a reverse screw rod 31, the two ends of which are respectively threadedly connected to the two sides of the movable support 1, and the reverse screw rod 31 is driven to rotate by the driving member 4. The reverse screw rod 31 passes through the screw rod mounting seat 33 and is connected to the movable support 1 through the screw rod nut 32. The trolley chassis 2 is symmetrically arranged along the reverse screw rod 31, so as to ensure the balance of the transfer trolley and ensure that the longitudinal beam on the transfer trolley does not shake or sink.

[0028] Screw mounting seats 33 are provided at both ends of the trolley chassis 2, and the screw is inserted into the screw mounting seats 33. The screw mounting seats 33 are used to adjust and limit the moving direction of the screw to avoid uneven force and deviation on both sides of the screw when used for a long time. The screw mounting seats 33 can be any as long as they can limit the screw, and the screw mounting seats 33 can be mounting holes or linear bearings.

[0029] Each end of the slide rail 11 and the slideway 21 is equipped with two sets of self-lubricating nylon sliders 5 to reduce the friction during the movement of the slide rail 11 and prevent derailment.

[0030] A scale 12 is provided on the outside of the slide rail 11 , and the scale 12 corresponds to the longitudinal beam model. The outer overlapping line of the slide rail 11 and the slideway 21 is used as a reference for movement and positioning.

[0031] like Figure 5 As shown, the driving member 4 includes a motor 41 and a reducer 42, and the motor 41 and the reducer 42 are arranged on the trolley chassis 2 through the support 23, and the output end of the reducer 42 is connected to the reverse screw rod 31 through the transmission belt 43, and the reverse screw rod 31 is provided with a transmission sprocket 311, and the transmission belt 43 is arranged on the outside of the transmission sprocket 311, and the motor 41 is connected to the reducer 42.

[0032] The trolley chassis 2 uses I-beam as the lower support, has good structural properties, and is compatible with the friction roller belt of the longitudinal beam line. The trolley chassis 2 is provided with anti-collision blocks 22 on both sides perpendicular to the direction of the two moving supports 1 to prevent the longitudinal beam from falling off.

[0033] A control switch is also included, and the control switch is connected to the motor 41.

[0034] The motor 41 is turned on by the control switch, and the motor 41 drives the reducer 42 to rotate. The output end of the reducer 42 drives the reverse screw rod 31 to rotate through the transmission belt 43, and the movable supports 1 on both sides move toward each other or in a direction of being close to each other or in a direction of being close to each other, so as to adjust the relative distance between the two movable supports 1.

[0035] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood by specific circumstances.

[0036] The above is only a preferred implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
