Description

A steel coil transport trolley

technical field

The utility model relates to a steel coil transportation device in a steel strip production line, in particular to a steel coil transportation trolley with double saddles. the

Background technique

In the strip steel production line, steel coil transportation is a key part of the entire logistics of the workshop, and the steel coil transportation trolley plays a vital role in the entire steel coil transportation system. There are many ways to transport steel coils, including: walking beam transportation, transportation chain transportation, steel coil trolley transportation and even driving hoisting. However, for the logistics system with a large transportation distance, the steel coil transportation trolley has become the preferred steel coil transportation solution due to its superior economy and reliability. the

At present, the existing steel coil transport trolley is only equipped with a lifting saddle without a fixed saddle, or only has a fixed saddle without a lifting saddle. , fixed saddles, etc.) to realize direct transfer of steel coils, for example: for the transfer of steel coils between fixed saddles and walking beams (or walking beams and transport chains), a transfer saddle must be added, thus increasing the A process and corresponding equipment. At the same time, for the steel coil transport trolley with single saddle, due to the limitation of the structure of the walking beam (or steel coil saddle and transport chain), the width of the saddle is smaller compared with the overall size of the steel coil, resulting in In the process of walking, the trolley requires high stability and cannot run at high speed, which limits the logistics speed of the workshop and affects the production rhythm. the

Utility model content

The purpose of the utility model is to provide a steel coil transport trolley with a lifting saddle and a fixed saddle at the same time. the

In order to achieve the above purpose, the following technical solutions are adopted:

A steel coil transportation trolley, comprising a fixed saddle arranged on the vehicle body, the lower part of the vehicle body is provided with a running device, and the feature is that: the vehicle body is also provided with a piston that is compatible with the hydraulic cylinder in the hydraulic lifting device Lifting saddles connected by rods.

In order to ensure the stable movement of the lifting saddle in the vertical direction, the bottom of the lifting saddle is provided with a guide rod, and the vehicle body is provided with a guide hole for the guide rod to extend into. the

In order to meet the requirements of long stroke and high running speed, the vehicle body is provided with a hydraulic station connected with the hydraulic cylinder on the hydraulic lifting device. the

The beneficial effect of the utility model is that: the trolley is equipped with a lifting saddle and a fixed saddle at the same time, which can simultaneously meet the transfer of steel coils between the trolley and the fixed saddle and the transfer of steel coils between the trolley and the walking beam conveyor; In the process, for the steel coil transportation between the non-walking beam and the walking beam, one process is reduced, and the transfer saddle is reduced, which effectively improves the production rhythm and equipment cost; at the same time, the width of the fixed saddle can be adjusted according to The external dimension of the steel coil needs to be lengthened and widened, which greatly improves the stability of the steel coil on the steel coil trolley, and can meet the requirements of the high-speed operation of the steel coil trolley. the

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is further described:

Embodiment 1: As shown in Fig. 1 and Fig. 2 : at this time, the steel coil is the incoming material in the axial direction, and the moving direction of the steel coil is parallel to the axial direction.

A steel coil transportation trolley, including a fixed saddle 3 arranged on a car body 7, a running device 2 is arranged on the lower part of the car body 7, and a piston rod on the hydraulic lifting device 6 is also arranged on the car body 7 Linked lifting saddle 4. The bottom of the lifting saddle 4 is provided with a guide rod 5, and the car body 7 is provided with a guide hole for the guide rod 5 to extend into. The vehicle body 7 is provided with a hydraulic station connected to the hydraulic cylinder on the hydraulic lifting device 6 . The upper end faces of the fixed saddle 3 and the lifting saddle 4 are V-shaped. the

Among them, the lifting saddle 4 is a welded steel structure, which is connected with the guide rod 5 of the hydraulic lifting device 6, and can be lifted and lowered under the drive of the hydraulic cylinder piston rod, and is used to receive steel from the fixed seat 1 (or walking beam, transport chain). roll. the

The fixed saddle 3 is a welded steel structure, fixed on the car body 7 of the steel coil trolley, and used to support the steel coils received by the lifting saddle 4; the length and width of the fixed saddle 3 can be designed according to the external dimensions of the steel coil, It can meet the requirement of high-speed operation of the steel coil trolley; at the same time, after the fixed saddle 3 accepts the steel coil, the lifting saddle continues to descend to leave a space, which can meet the requirements of the walking beam to directly receive the coil from the steel coil trolley. the

The hydraulic lifting device 6 mainly includes a hydraulic cylinder, a hydraulic cylinder support and a guide rod. The piston rod of the hydraulic cylinder and the guide rod are connected with the lifting saddle 4, and can be lifted and lowered in the vehicle body under the drive of the piston rod of the hydraulic cylinder; There are small hydraulic stations that power the hydraulic cylinders. the

The car body 7 is a welded steel structure, used to support the entire steel coil trolley, and is provided with a guide hole, so that the guide rod 5 of the hydraulic lifting device can be raised and lowered in the guide hole. the

The running gear mainly includes gear motors, sprockets, wheel devices and tracks. The gear motor drives the wheel device through the sprocket, and the wheel device is installed on the car body, so that the steel coil trolley can walk on the track and transport the steel coil to the designated position. the

Embodiment 2: As shown in Figure 3 and Figure 4, the difference from Embodiment 1 is that the steel coil is an axial incoming material, and the direction of movement of the steel coil is parallel to the radial direction. At this time, the fixed saddle 3 and the lifting saddle 4 are aligned with the Compared with Embodiment 1, it is rotated by 90 degrees to adapt to the change of the steel coil. the

The utility model is provided with a lifting saddle and a fixed saddle, which can meet the transfer of steel coils between the trolley and the fixed saddle and the transfer of steel coils between the trolley and the walking beam conveyor (or steel coil saddle and transport chain), and It can meet the requirements of high-speed operation of steel coil trolley. the
