During the excavation of inclined shafts, the efficiency of personnel and material transportation significantly impacts the excavation progress. Traditional transportation equipment is often limited in function, typically transporting only materials or personnel in a single trip, resulting in low efficiency. Even equipment capable of transporting both personnel and materials simultaneously faces challenges in lowering them to the working face, and having both personnel and materials in the same transport compartment increases the risk of collisions and injuries, jeopardizing worker safety. Utility Model Content:

[0003] The purpose of this utility model is to solve the problems existing in the above-mentioned technical field and provide a multi-functional transport trolley for inclined shaft expansion, which has the characteristics of diverse transport functions, stable transport capacity and high loading and unloading efficiency.

[0004] To achieve the above objectives, this utility model adopts the following technical solution:

The inclined surface of the vehicle frame matches the inclination angle of the inner wall of the inclined shaft. Lifting lugs are provided at the top of the inclined surface of the vehicle frame. The transport platform is fixedly installed on the top of the vehicle frame. The transport platform includes a platform steel plate, guardrails, and a detachable partition fence. The platform steel plate has a rectangular structure and is fixedly connected to the top of the vehicle frame on all four sides. The guardrails are fixedly installed around the transport platform, and personnel can enter through the guardrails. An entrance door is provided at the exit location; the removable partition fence is telescopic and is fixed to the guardrail with buckles, allowing for free division of the transport platform space; the platform steel plate has unloading holes and manholes, both of which are equipped with openable covers; an unloading channel is fixedly installed on the inclined surface of the vehicle frame below the unloading hole, and a pedestrian ladder is fixedly installed on the inclined surface of the vehicle frame below the manhole; the walking mechanism is symmetrically installed on both sides of the inclined surface of the vehicle frame, and the walking mechanism includes fixed steel plates and walking wheels. The walking wheels are installed on the fixed steel plates, which are installed on the I-beams on both sides of the inclined surface of the vehicle frame, and the walking wheels are installed on the inclined surface of the vehicle frame through the fixed steel plates.

[0006] The vehicle body frame is made of Q345B high-strength steel. 16 It is made of welded I-beams and square steel, with dimensions of 3.5 meters long, 2.676 meters wide, and 2.767 meters high.

[0007] The aforementioned walking mechanism consists of four symmetrically arranged components.

[0008] The diameter of the wheels is 300 mm.

[0009] The platform steel plate is made of 5mm thick patterned steel plate; the size of the platform steel plate matches the size of the top surface of the vehicle frame, and it is welded and fixed to the top square steel of the vehicle frame on all four sides.

[0010] The platform steel plate is provided with an 80×78 cm unloading hole and an 80×78 cm manhole.

[0011] The guardrail is 1.2m high and is made of steel pipe with a diameter of 50mm. The bottom is welded and fixed to the top I-beam of the vehicle frame.

[0012] The guardrail is equipped with a 20-centimeter-high kick plate at the bottom, which is made of 5mm thick patterned steel plate and welded to the platform steel plate; the upper part of the guardrail is surrounded by a protective netting.

[0013] The unloading channel is made of 5mm thick patterned steel plate, which is welded and fixed to the I-beams on the inclined surface of the vehicle frame below the unloading hole.

[0014] The pedestrian ladder uses stainless steel steps with a diameter of 16mm, which are welded and fixed to the I-beams on the inclined surface of the vehicle frame below the manhole.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. Traditional transportation equipment has a single function, typically transporting materials or personnel only once, resulting in low efficiency, a high risk of collisions, and compromised worker safety. Compared to other conventional inclined shaft transport trolleys, this invention uses detachable partitions to freely divide the transport platform, enabling simultaneous transport of personnel and materials. This ensures that materials are promptly categorized and managed upon arrival, avoiding the risk of people standing below during material transport.

[0017] 2. This utility model provides a pedestrian ladder on the inclined surface of the vehicle frame below the manhole, allowing direct access to the work platform through the manhole. It is safe and reliable during passage and requires no additional auxiliary measures.
