[0026] Example

[0027] The conveying distance of the currently known belt conveyor equipment is fixed during manufacturing, and it is a site-adaptive equipment during use. If the belt conveyor is too long or too short during use, it will affect the transportation efficiency of the goods. Moreover, the fixed-length conveying distance can only be used within the specified range, which has great limitations. For this reason, we propose a belt conveyor equipment that can implement stepless telescopic adjustment without stopping.

[0028] like Figure 1-3 As shown, a telescopic belt conveyor disclosed in this embodiment includes a main frame 1, a sub-frame 2 and a conveying belt 3, and the main frame 1 and the sub-frame 2 are slidably matched to form a whole; the main frame 1 includes a mounting frame 101, and side panels 102 are installed on the tops of both sides of the mounting frame 101, and sliding rails 103 are horizontally fixed on the bottoms of the opposite sides of the two side panels 102, and a driving roller 106, a first passive roller 107 and a second transition roller 108 are rotatably installed between the tail ends of the two side panels 102 through seat bearings, and a supporting wheel 105 and a first transition roller 104 are rotatably installed at the middle positions of the front ends of the two side panels 102 through seat bearings, and a belt drive motor 109 and a frame telescopic drive mechanism are installed at the bottom of the inner side of the mounting frame 101; at the same time, micro switches 116 are installed at the bottoms of both ends of the two side panels 102, and the setting of the micro switches 116 is mainly to control the telescopic limit distance of the sub-frame 2 to avoid excessive displacement and damage to the equipment.

[0029] like Figure 3-5 As shown, the belt drive motor 109 and the end of the transmission roller 106 are driven by a drive chain; the auxiliary frame 2 includes two mounting beams 201, and the two mounting beams 201 are respectively slidably fitted on the inner wall of the side plate 102, and the second passive roller 208 and the third transition roller 203 are respectively rotatably mounted between the two ends of the two mounting beams 201 through seat bearings, and the front end bottoms of the two mounting beams 201 are both installed with pulley support arms 209, and the bottoms of the two mounting beams 201 are rollingly matched with the supporting wheels 105.

[0030] like Figure 3-4 As shown, the frame telescopic drive mechanism includes a telescopic drive motor 110 installed at the bottom of the mounting frame 101 and close to the belt drive motor 109; the frame telescopic drive mechanism also includes a drive shaft 112 installed at the bottom of the mounting frame 101 through a main gear frame 111 for horizontal rotation, and transmission chains 115 are installed at both ends of the drive shaft 112 and are located on both sides of the mounting frame 101 for meshing transmission. Adjustment sprockets 114 are installed on both sides of the bottom of the front end of the mounting frame 101 through sub-gear brackets 113. The two transmission chains 115 are respectively meshed with the two adjustment sprockets 114 for transmission. The telescopic drive motor 110 is connected to the drive shaft 112 for transmission. A connecting frame 207 is installed between the two transmission chains 115, and the top of the connecting frame 207 is fixedly installed to the tail ends of the two mounting beams 201.

[0031] like Figure 2 As shown, the No. 1 transition roller 104 and the No. 2 transition roller 108 are arranged at the same height position, the No. 3 transition roller 203 and the driving roller 106 are arranged at the same height position, the No. 1 transition roller 104, the driving roller 106, the No. 1 passive roller 107, the No. 2 transition roller 108, the No. 3 transition roller 203 and the No. 2 passive roller 208 are parallel, and the conveying belt 3 passes through the No. 1 passive roller 107, the No. 2 passive roller 208, the No. 3 transition roller 203, the No. 1 transition roller 104, the No. 2 transition roller 108 and the driving roller 106 in sequence to form a closed loop.

[0032] In this embodiment, the structural design of the main frame 1 and the auxiliary frame 2 makes the two belt conveyor mechanisms perfectly integrated, and the telescopic drive motor 110 cooperates with the transmission chain 115 to drive and control the telescopic length between the main frame 1 and the auxiliary frame 2, and with the help of multiple sets of transition rollers and passive rollers, the conveyor belt 3 can always maintain an effective tension during the telescopic adjustment of the main frame 1 and the auxiliary frame 2, and the purpose of stepless adjustment can be achieved without shutting down the equipment, effectively improving the adaptability of the belt conveyor equipment to the use scenario, reducing the use limitations, and thus achieving the purpose of improving the efficiency of cargo transportation.

[0033] like Figure 3-5 As shown, in order to form a stable telescopic fit between the main frame 1 and the auxiliary frame 2 and facilitate the deployment of the auxiliary frame 2 from the main frame 1, upper guide grooves 119 of horizontal design are integrally formed on the tops of the two side panels 102, and side guide wheels 205, upper guide wheels 204 and lower guide wheels 206 are rotatably installed at the tail ends of the two mounting beams 201. The side guide wheels 205 on the two mounting beams 201 are respectively rollingly fitted with the two side panels 102, and the upper guide wheels 204 and lower guide wheels 206 on the two mounting beams 201 are respectively rollingly fitted with the upper guide grooves 119 and the sliding rails 103.

[0034] like Figure 1-3 As shown, in order to improve the load-bearing capacity of the belt conveyor, a first surface cover 118 is horizontally installed between the two upper guide grooves 119 , and a second surface cover 202 is horizontally installed between the tops of the two mounting beams 201 .

[0035] In order to ensure smooth expansion and contraction between the main frame 1 and the auxiliary frame 2, Figure 1-4As shown, an adjusting assembly 117 is installed on the axle of the adjusting sprocket 114, wherein the adjusting assembly 117 includes a long bolt, one end of the long bolt with a nut is clamped on one side of the axle of the adjusting sprocket 114, and one end of the long bolt slides through the axle of the adjusting sprocket 114 and the sub-gear bracket 113 respectively, and a nut is threadedly assembled thereon. By screwing the nut and cooperating with the long bolt, the horizontal position of the adjusting sprocket 114 on the sub-gear bracket 113 is adjusted, thereby adjusting the tension of the transmission chain 115, thereby achieving a stable telescopic adjustment driving effect.

[0036] When the entire belt conveyor is telescopic, the telescopic drive motor 110 drives the drive shaft 112 to rotate, thereby rotating the two transmission chains 115 installed between the drive shaft 112 and the adjustment sprocket 114. With the help of the rotation of the transmission chain 115, the connecting frame 207 drives the auxiliary frame 2 to perform telescopic movement at the front end of the main frame 1, thereby achieving the purpose of adjusting the length of the belt conveyor. During the movement of the auxiliary frame 2, the movement of the third transition roller 203 and the distance between the first transition roller 104 produce an extension / contraction change, and at the same time, the same distance of extension / contraction changes are produced between the first passive roller 107 and the second passive roller 208, forming a distance compensation difference between each other. Therefore, the main frame 1 and the auxiliary frame 2 do not need to adjust the tension of the conveyor belt 3 during the telescopic adjustment process, so as to achieve the effect of standby adjustment, which is extremely convenient to use and realizes the effect of equipment adapting to the site.

[0037] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
