Description

Technical Field

[0001] This utility model relates to the technical field of steel bar transportation equipment, and in particular to a remotely controlled self-propelled mobile steel bar transportation trolley. Background Technology

[0002] Highway construction, especially bridge and culvert projects, typically requires large quantities of steel to support construction progress. However, due to terrain limitations, construction sites often cannot store large amounts of steel. To ensure construction progress and the quality and precision of rebar processing, projects typically construct rebar processing plants in suitable locations to improve production efficiency. Similarly, when the bridge superstructure includes precast box girders, a box girder prefabrication plant is needed to process and precast the girder segments. Therefore, rebar transportation becomes a crucial link. Currently, the transportation of these semi-finished rebar products on-site relies solely on equipment such as gantry cranes and forklifts. This method has drawbacks: low transportation efficiency, limited capacity per transport, and the potential for injury to nearby workers during transport, posing significant safety hazards. Therefore, designing a new type of rebar transport vehicle to improve rebar transportation efficiency is an urgent task. Utility Model Content

Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0034] like Figure 1 and Figure 2 As shown, a remotely controlled self-propelled mobile rebar transport trolley includes: a remotely controlled trolley body, set on a track in the work area; two fixed guardrails 5, set on the left and right sides of the remotely controlled trolley body; two folding guardrails 6, rotatably set on the front and rear sides of the remotely controlled trolley body; and an audible and visual alarm 15, set on the side wall of the remotely controlled trolley body. The remotely controlled trolley body includes: a trolley flatbed 1; two transmission bearings 8, respectively set on the front and rear sides of the bottom of the trolley flatbed 1; four steel wheels 9, respectively set on the two transmission bearings 8; two drive systems 2, respectively set on the two transmission bearings 8, for driving the transmission bearings 8 to rotate; a control system 3, set on the trolley flatbed 1 and connected to the drive systems 2, and equipped with a remote controller; and a battery pack 4, set inside the trolley flatbed 1, supplying power to the drive systems 2, control system 3, and audible and visual alarm 15. The drive system 2 consists of a motor 7 and a reduction gear assembly mounted thereon. This utility model also includes: a brake 10, set on the trolley flatbed 1, for locking the steel wheels 9. The control system 3 includes: a control box 11, installed inside the trolley flatbed 1 and connected to the start / stop control section of the drive system 2; a inverter 12, connected to the control box 11 and to the forward / reverse start section of the drive system 2; and an air switch 13, installed on the trolley flatbed 1 and connected to the control box 11. This invention also includes a charging port 14, installed on the trolley flatbed 1 and connected to the charging section of the battery pack 4.

[0035] In use, this utility model can move, change direction, and brake on the track via a remote controller. The specific operation method is as follows:

[0036] This utility model mainly consists of a trolley flatbed 1, a drive system 2, and a control system 3.

[0037] The trolley flatbed 1 is equipped with fixed guardrails 5, folding guardrails 6, and an audible and visual alarm 15. The fixed guardrails 5 are 30cm high and installed on both sides of the trolley flatbed 1. They are vertically welded from seamless steel pipes with an inner diameter of 24mm. To prevent the transported goods from tipping over, steel pipes with an inner diameter of less than 24mm or plain round steel bars can be inserted to increase the transport height, within safe limits. The folding guardrails 6 are 50cm high and installed on the front and rear sides of the trolley flatbed 1. They can be folded parallel to the track direction to be horizontal to the top surface of the trolley flatbed 1 to expand the longitudinal transport capacity. The audible and visual alarm 15 automatically activates when the trolley flatbed 1 is powered on.

[0038] The drive system 2 consists of a motor 7, a transmission bearing 8, steel wheels 9, and a brake 10. The drive system 2 uses two 0.8kW motors 7, which transmit power to the steel wheels 9 via the transmission bearings 8, enabling the trolley flatbed 1 to move along the track. It employs a four-wheel drive system to prevent slippage when the trolley is empty. The four steel wheels 9 use only one side (inner side) of the wheel to move along the track, making adjustment easier, especially at track intersections. The inner diameter of the two inner steel wheels 9 is 112cm, and they are equipped with brakes 10 to provide stability when loading and unloading materials such as steel bars. After the trolley flatbed 1 has completed its journey, the brakes 10 lock the steel wheels 9 to ensure the stability of the trolley body during material loading and unloading.

[0039] The control system 3 consists of a control box 11, a converter 12, an air switch 13, and a charging port 14. The control box 11 can adjust the speed of the trolley flatbed 1 and also check the trolley's battery level; the converter 12 can control the trolley's forward direction via a remote controller; the air switch 13 is in the open state when the trolley is in use and should be turned off promptly after use; this utility model uses a charging method to provide energy and is equipped with a 220V interface charger, which can be plugged into the charging port 14 to charge.

[0040] After the air switch 13 is turned on, the trolley's forward, reverse, and braking functions can be operated using the remote control. The remote control is also equipped with an emergency brake button to ensure passive protection in case of emergencies. To prevent unauthorized operation, this invention recommends a dedicated management system. The remote control is equipped with a safety device that can only be operated by a qualified operator after the safety device has been unlocked with a key; otherwise, the steel bar transport trolley cannot be used.

[0041] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
