Therefore, when the cementing operation position is changed, there is no need to arrange an additional transport vehicle to transport the cable and the roller 4. When the mounting frame 3 is in an adjustment state, the relative position of the roller 4 and the carrier 1 can be adjusted, and the roller 4 and the mounting frame 3 can be separated from the carrier 1, so that the roller 4 can be placed at a suitable position at the cementing site, which is convenient for laying the cable.

[0063] Specifically, the cementing vehicle also includes a protective structure, the position of which is adjustably arranged at the periphery of the bearing part of the carrier 1, and the protective structure has a protective position and a supporting position.

With such a structural arrangement, when the cementing vehicle is in a transport state, the protective structure can be placed in the protective position, so that the cementing equipment carried on the carrier 1 can be protected by the protective plate; when the roller 4 needs to be removed, the protective structure can be placed in the supporting position, so that the protective plate is supported on the ground by the support member, thereby facilitating the transfer of the roller 4 from the carrier 1 to the ground through the protective plate, which effectively reduces the difficulty of moving the roller 4 and reduces the labor cost of the workers.

The setting of the first manifold system 23 facilitates the transportation of cement slurry. The combination of the mixing system 21, the plunger pump system 22 and the first manifold system 23 can efficiently complete the mixing, transportation and discharge of cement slurry, effectively improving the efficiency of cementing work.

[0070] Specifically, the first manifold system 23 is a high-pressure manifold system, which facilitates the transportation of cement slurry pressurized by the plunger pump system 22 .

[0071] Specifically, the cementing operation equipment 2 further includes a power transmission system 24, which is arranged on the vehicle 1, and the power transmission system 24 is arranged on a side of the plunger pump system 22 away from the rear of the vehicle 1, and the power transmission system 24 is in transmission connection with the plunger pump system 22.

The hydraulic system 25 is driven by the auxiliary frequency conversion integrated machine on the platform through the transfer case, and four groups of hydraulic pumps are installed on the transfer case; the first group is a double vane pump, the front pump is a circulating hydraulic pump, and the rear pump is a stirring or ash or clean water hydraulic pump; the second group is a double vane pump, the front pump is an injection hydraulic pump, and the rear pump is a radiator hydraulic pump; the third group is a double vane pump, the front pump is a perfusion hydraulic pump, and the rear pump is a power end lubrication hydraulic pump; the fourth group is a single vane pump, which is a water supply hydraulic pump. The four groups of hydraulic pumps drive the centrifugal pump motor, the stirring motor, the radiator and the metering tank system 210 and the ash loading system 27 through hydraulic valves and pipelines respectively. The pressure and flow of the hydraulic system 25 are reasonably matched and can meet the use of the above systems. The hydraulic system 25 has a radiator and an electric heater device to adapt to the working environment requirements with large temperature differences in winter and summer.

[0075] In this embodiment, the hydraulic system 25 includes an on-stage hydraulic motor, a first transfer case, a second transfer case, a third transfer case and a fourth transfer case. The on-stage hydraulic motor is drivingly connected to the first transfer case, the second transfer case, the third transfer case and the fourth transfer case, and the on-stage hydraulic motor drives the first transfer case, the second transfer case, the third transfer case and the fourth transfer case to work.

[0076] Specifically, the hydraulic system also includes: motors, control valves, pipelines, oil tanks, etc., and each component is also distributed in different positions, such as hydraulic pumps on the platform and chassis, hydraulic motors on various loads, drum motors on drums, centrifugal pump motors on centrifugal pumps, etc. The control valve is installed in an easy-to-operate position, and the pipeline is the oil circuit connecting the various components.

[0078] like Figure 5 and Figure 6 As shown, the cementing operation equipment 2 also includes a brake structure 26, which is arranged on the carrier 1 and connected to the power transmission system 24. In this way, it is convenient to control the power transmission system 24 through the brake structure 26, and emergency braking can be performed when necessary to achieve fine control of cementing operation pressure. Specifically, when the second motor 241 of the power transmission system 24 is powered off, due to the large rotational inertia of the rotor of the second motor 241, the rotor needs a certain amount of time to stop rotating, and the stopping time varies from tens of seconds to several minutes. The specific time depends on the power of the second motor 241. Generally, the greater the power of the second motor 241, the longer the rotor stops after power failure. During the process of the second motor 241 rotating due to inertia, the output shaft of the second motor 241 still rotates, and then drives the plunger pump to rotate through the transmission shaft, so the plunger pump still has high-pressure liquid output, which brings safety hazards to the on-site operation. After adding the brake structure, when the operation is terminated or the plunger pump needs to stop pumping high-pressure liquid due to an emergency, the output shaft of the motor can be immediately stopped by the brake structure.

[0079] Specifically, the cementing operation equipment 2 also includes a mixing system 21, a plunger pump system 22, a power transmission system 24 and a hydraulic system 25.

With such a structural arrangement, it is possible to facilitate the corresponding movement of the brake caliper 262 through the oil pressure of the hydraulic system, thereby facilitating the braking operation.

[0080] Specifically, the brake caliper 262 includes a hydraulic cylinder, and the hydraulic drive oil circuit is connected to the hydraulic cylinder. When braking is required, the brake solenoid valve is activated to supply hydraulic oil to the hydraulic cylinder at a certain distance, and the hydraulic oil pushes the hydraulic cylinder inside the brake caliper 262 to operate. After the hydraulic cylinder extends, it rubs against the brake flange, and through the friction torque, the output shaft of the second motor 241 stops rotating.

[0081] Specifically, the cementing operation equipment 2 further includes a ash loading system 27 , which is used to transport dry ash to the equipment and supply it to the mixing system 21 .

[0086] Specifically, the cementing vehicle also includes a chassis system, which can provide hydraulic power for the entire cementing vehicle and provide an air source for the air circuit system. It is mainly composed of a chassis vehicle, a sub-beam support frame, and a transfer case. The transmission shaft is connected to the hydraulic system 25 through the full-power power take-off of the chassis vehicle, and then connected to the hydraulic system 25 through bolts, and the output torque drives the hydraulic pump; the air module taken from the chassis vehicle is connected through the air circuit connector and pipeline to provide an air source for the butterfly valve and purge on the platform.
