However, the gantry truss mechanism requires long passageways on both sides of the stockpiled materials or train / truck carriages for installation, which takes up more ground space. It is not suitable for installing and using the gantry truss mechanism in narrow ground conditions or limited spaces. Therefore, there is an urgent need for a truss structure that can overcome the above-mentioned defects as a supplement for material sampling sites. Utility Model Content

[0064] See Figure 3 and Figure 4 , Figure 3 This is a schematic diagram of the cantilever beam mechanism 2 and the sampling translation mechanism 3 according to an embodiment of the present invention. Figure 4 for Figure 3 Another view. The cantilever beam mechanism 2 in this embodiment includes a cantilever steel beam 21, an upper guide rail 22, a lower guide rail 24, and a steel beam rack 23.

The translation motor is connected to the translation gear via the reducer, and the translation gear meshes with the steel beam rack 23.
[0066] See Figure 5 , Figure 5This is a schematic diagram of the truss track 4 according to an embodiment of the present invention. The truss track 4 in this embodiment includes a bottom track 41, a track foundation steel beam 42, and an anti-tipping track 43. The track foundation steel beam 42 is installed on a ground foundation, and the bottom track 41 is installed on the track foundation steel beam 42; the anti-tipping track 43 is installed on the outside of the bottom track 41.
[0067] This utility model can be installed in a narrow area, equipped with a sampler 6, to automatically and randomly sample crushed materials such as coal and ore piled on the side or loaded on a vehicle. The cantilever truss can be automatically moved horizontally along the ground track by an automatic control system or a manual operation controller through the truss control mechanism 5. The sampler 6 can be moved laterally along the straight track on the cantilever beam mechanism 2. Within the reach of the movement, the lower sampling head of the sampler 6 automatically extends vertically downward to automatically sample the material on the side of the truss (which is also below the sampling head). After sampling, the sampling head retracts vertically upward, and the material sample with a certain weight moves laterally along the track of the cantilever beam mechanism 2 on the cantilever truss to the sample collection box on the other side of the truss. The material sample is placed in the sample collection box (the sample collection box transports the material sample along the conveyor line). At this point, the movement coordination between the cantilever truss and the sampling head ends, and the truss moves to the next material position to perform the same sampling process.
[0068] In one embodiment of this utility model, the support 11 of the main frame 1 is preferably a main steel beam structure, equipped with truss bottom support rollers 122, which roll along the bottom rail 41 of the truss track 4 to achieve linear movement of the entire truss; due to the off-center load characteristics of the cantilever truss working load, in order to prevent the whole machine from tipping over during operation, anti-tipping plates 13 are added to both ends of the bottom of the main frame 1, and anti-tipping roller mechanisms 14 are added to both sides; the opening K3 at the lower part of the anti-tipping plate 13 is similar in shape to the end face of the bottom rail 41, that is, the opening of the anti-tipping plate 13 always engages with the bottom rail 41 without contacting the guide rail, thus playing a role in tipping protection; the upper end of the roller of the anti-tipping roller mechanism 14 contacts the lower rail surface K2 of the anti-tipping track 43, and the roller of the anti-tipping roller mechanism 14 rolls along the lower rail surface of the anti-tipping track 43 and bears the tipping force of the cantilever truss at any time, thus achieving the overall The mechanism is subjected to force balance. In addition, to meet the working load requirements, the main frame 1 and the cantilever beam mechanism 2 adopt a rigid structure. At the same time, cantilever beam connectors 154 are added to both ends of the cantilever beam mechanism 2. Connecting pins 155 connect the first cantilever diagonal bracing beam 152 and the second cantilever diagonal bracing beam 153 on both sides to the cantilever steel beam 21 and the support 11 for connection and reinforcement. The diagonal bracing beam adjustment seat 151 is used to adjust the position of the pin hole during the connection process to ensure the balance of the tension of each diagonal bracing beam. The above structure improves the overall rigidity of the cantilever truss under working load. The support roller power chain 124, support roller shaft sprocket 123, motor reducer and power sprocket constitute the power transmission to realize the movement of the truss. The truss control mechanism 5 is used to realize the motion control of the truss as a whole and the sampling machine 6 (including lateral movement and positioning) and the sampling action process control.
[0069] Two cantilever steel beams 21 of the cantilever beam mechanism 2 are installed horizontally and parallel to each other on the upper part of the main frame 1. The upper guide rails 22 of the two upper steel beams and the lower guide rails 24 of the two lower steel beams are kept parallel. A steel beam rack 23 is installed on the side of one of the cantilever steel beams 21, which meshes with the gear of the translation drive component 33 on the sampling translation mechanism 3. There are two sets of translation rollers 32 on each side of the sampling mounting plates 31 on both sides of the sampler 6. The translation rollers 32 make roller contact with the upper guide rail surface and the side guide rail surface of the upper guide rail 22 of the steel beam, respectively. At the same time, the lower guide rail 24 of the steel beam makes contact with the translation guide constraint roller 34 on the lower guide rail surface K4. That is, the above roller sets realize the vertical and horizontal constraints of the sampling translation mechanism 3. The sampler 6 installed on the sampling translation mechanism 3 can only move linearly back and forth along the cantilever beam mechanism 2, and can withstand the sampling working load (sampling rotation force, insertion force, etc.). The bottom track 41 of the truss track 4 structure is fixed on the track foundation steel beam 42 to maintain horizontality and parallelism. The track foundation steel beam 42 is fixed on the ground foundation to maintain rigid constraint. Anti-tipping track 43 is installed on its side, with the track surface facing downward and contacting the rollers of the anti-tipping roller mechanism 14 to realize the anti-tipping function of the truss.
[0070] This utility model's cantilever truss is installed on one side of the stacked or vehicle-loaded crushed materials such as coal and ore. Equipped with a sampler 6 and used in conjunction with a sample collection box and a sample delivery line, it enables fully automated sampling of materials on the side. It achieves automatic random material sampling of crushed materials such as coal and ore stacked or vehicle-loaded on the side. When crushed materials such as coal and ore are stacked on the side of the cantilever truss, or when a material transport vehicle stops its cargo compartment on the side of the truss, the motor reducer and power sprocket drive the support roller power chain 124 to transmit power to the support roller shaft sprocket 123, pulling the bottom support roller 122 of the truss to roll on the bottom track 41, thus moving the entire cantilever truss along the truss track 4. When the cantilever truss... After the entire assembly moves to the designated position and stops, the sampler 6, mounted on the sampling mounting plate 31, rotates with the translation motor reducer and gears and meshes with the steel beam rack 23 to move along the cantilever steel beam 21 to its designated position. The sampling head K1 at the bottom of the sampler 6 descends and inserts into the material to sample it. The insertion sampling process requires a certain sampling rotation force and insertion force. After the sampling head K1 completes the sampling, it moves upward and retracts back to its original position. The translation motor reducer and gears rotate, and the sampling head K1 moves along the cantilever steel beam 21 to the other side of the truss. After it is in place, the sampling head K1 descends again and releases the collected material sample into the corresponding sample collection box at the bottom. The sample collection box is then transported away, and the sampling head K1 returns to its original position to continue the next sampling process.
[0071] This utility model can be equipped with a sampling machine 6 and used in conjunction with a sample receiving box and a sample delivery conveyor line to achieve a fully automated sampling process for side materials; it can realize the function of automatic random material sampling of crushed materials such as coal and ore piled on the side or loaded on a vehicle; all parts are integrated, and the sampling work of materials at random locations is carried out through an automatic control system or a manual operation controller. This cantilever truss structure is simple, easy to install, operate and maintain, and can be serialized according to the working load and working range.
[0072] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
