Description

Technical Field

[0001] This invention relates to the field of rail transit technology, and in particular to an adjustable stacker-reclaimer track support structure. Background Technology

[0002] Stacker-reclaimers, as important stockpile operation equipment, are suitable for material storage yards in thermal power plants, cement plants, ports, mines, metallurgical plants, and large-scale water conservancy projects. They are efficient and capable of continuous operation for handling bulk materials. Due to the large load on the equipment, significant horizontal thrust is usually generated during production, causing lateral deformation of the tracks and leading to phenomena such as track jamming and pulley failure. Under the long-term action of heavy loads on stockpiled materials, the soil layer beneath the stacker-reclaimer foundation will undergo lateral compressive deformation, resulting in horizontal displacement of the foundation. The amount of deformation is determined by the foundation type and the properties of the underlying soil. Minor deformation can be adjusted through routine maintenance. However, in sites with low bearing capacity, excessive track deformation exceeding the range of routine maintenance adjustments will render the equipment inoperable, requiring foundation reconstruction. This will severely impact equipment use and production operation, significantly increasing production and operating costs. Summary of the Invention

[0003] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides an adjustable stacker-reclaimer track support structure. By opening a reserved groove and setting a clamping wooden block, the track adjustment deformation capacity is improved, and the problem of high production and operation costs caused by the overall modification of the stacker-reclaimer foundation when the deformation is too large is solved.

[0004] An adjustable stacker-reclaimer track support structure includes a stacker-reclaimer foundation, a precast concrete base, timber, and a track. The stacker-reclaimer foundation has a pre-reserved groove, the precast concrete base is placed inside the pre-reserved groove, and a plurality of timbers are placed between the precast concrete base and the sidewall of the precast groove. The two sides of the timbers abut against the precast concrete base and the sidewall of the precast groove, respectively. The track is located on the top of the precast concrete base.

[0005] By creating pre-reserved grooves and installing clamping timbers, the timbers on both sides provide lateral restraint on the precast concrete base, meeting the requirements for horizontal action. When the track or the precast concrete base deforms, the original timbers are removed, the position of the precast concrete base in the pre-reserved groove is adjusted, and timbers of appropriate size are inserted after the track is straightened. This achieves the adjustment of the track's lateral deformation and straightens it, improving the track's deformation adjustment capability and avoiding the need for overall modification of the stacker-reclaimer foundation.

[0006] Furthermore, the bottom of the reserved groove is filled with a precast beam leveling layer, and the precast concrete base is placed above the precast beam leveling layer.

[0007] By setting up a leveling layer for the precast beams, the bottom of the precast concrete base was leveled, meeting the accuracy requirements for the installation of the precast concrete base.

[0008] Furthermore, a rubber pad is provided on the top surface of the precast beam leveling layer, and the precast concrete base is placed on the rubber pad.

[0009] By installing rubber pads, the bottom of the precast concrete base is buffered, which reduces the impact on the equipment and ensures stable operation.

[0010] Furthermore, it also includes pre-embedded anchor bolts and track connectors, wherein the track is connected to the precast concrete base via the pre-embedded anchor bolts and track connectors, and the track connectors are elongated holes.

[0011] By using track connectors with elongated holes, small displacement adjustments can be achieved, requiring low precision of pre-embedded anchor bolts, and facilitating construction, installation, and daily maintenance.

[0012] Furthermore, the top surface of the precast concrete base is provided with a secondary grouting layer, and the track is connected to the surface of the secondary grouting layer.

[0013] By setting a secondary grouting layer between the track and the precast concrete base, the flatness of the track installation is improved.

[0014] Furthermore, the length of the hole in the elongated hole track connector is 3-5 times the diameter of the pre-embedded anchor bolt.

[0015] Furthermore, the distance between the precast concrete base and the side wall of the reserved groove is 120-150mm.

[0016] Furthermore, the spacing between adjacent timbers along the length of the track is 500-800mm.

[0017] The beneficial effects of this invention are: This invention discloses an adjustable stacker-reclaimer track support structure. By creating a pre-reserved groove and installing abutting timbers on both sides, the timbers provide lateral constraint on the precast concrete base, satisfying the requirements for horizontal action. When the track or the precast concrete base deforms, the original timbers are removed, the position of the precast concrete base in the pre-reserved groove is adjusted, and a timber of appropriate size is inserted after the track is straightened. This achieves the adjustment and straightening of the track's lateral deformation, improves the track's deformation adjustment capability, avoids the overall modification of the stacker-reclaimer foundation, and reduces production and operating costs.

[0018] By using track connectors with elongated holes, small displacement adjustments can be achieved, requiring low precision of pre-embedded anchor bolts, and facilitating construction, installation, and daily maintenance.

[0019] By installing rubber pads and a precast beam leveling layer under the precast concrete base, and a secondary grouting layer under the track, the flatness and buffering requirements of the track are met, greatly reducing the construction precision requirements and facilitating debugging and maintenance during production and operation.

[0022] To better explain and facilitate understanding of the present invention, it will be described in detail below with reference to the accompanying drawings and specific embodiments. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a clearer and more thorough understanding of the invention and to fully convey the scope of the invention to those skilled in the art.

[0023] like Figure 1-2 As shown, an adjustable stacker-reclaimer track support structure includes a stacker-reclaimer foundation 5, a precast concrete base 2, timber 4, and a track 1. The stacker-reclaimer foundation 5 has a reserved groove, the precast concrete base 2 is set inside the reserved groove, and a plurality of timber 4 are provided between the precast concrete base 2 and the side wall of the reserved groove. The two sides of the timber 4 abut against the precast concrete base 2 and the side wall of the reserved groove, respectively. The track 1 is set on the top of the precast concrete base 2.

[0024] By creating a pre-reserved groove and setting a tight wooden block 4, the wooden blocks 4 on both sides achieve lateral constraint on the precast concrete base 2, meeting the requirements of horizontal action. When the track 1 deforms or the precast concrete base 2 deforms, the original wooden block 4 is removed, the position of the precast concrete base 2 in the pre-reserved groove is adjusted, and after the track 1 is straightened, a wooden block 4 of appropriate size is placed in, realizing the adjustment of the lateral deformation of the track 1 and straightening it, improving the deformation adjustment capacity of the track 1, and avoiding the overall modification of the stacker-reclaimer foundation 5.

[0025] Specifically, the bottom of the reserved groove is filled with a precast beam leveling layer 9, and the precast concrete base 2 is placed above the precast beam leveling layer 9.

[0026] By setting up a precast beam leveling layer 9, the bottom of the precast concrete base 2 is leveled, meeting the accuracy requirements for the installation of the precast concrete base 2.

[0027] More specifically, the precast beam leveling layer 9 is made of 50mm thick fine aggregate concrete.

[0028] Specifically, the top surface of the precast beam leveling layer 9 is provided with a rubber pad 7, and the precast concrete base 2 is placed on the rubber pad 7.

[0029] By setting rubber pads 7, the bottom of the precast concrete base 2 is buffered, which reduces the impact on the equipment and ensures stable operation of the equipment.

[0030] More specifically, the rubber pad 7 has a thickness of 20 mm.

[0031] Specifically, it also includes pre-embedded anchor bolts 3 and track connectors 6. The track 1 is connected to the precast concrete base 2 above the track 1 through the pre-embedded anchor bolts 3 and track connectors 6. The track 1 connector is an elongated hole.

[0032] By setting the track connector 6 with an elongated hole, small displacement adjustments can be achieved, the precision requirements for the pre-embedded anchor bolt 3 are low, and it is convenient for construction, installation and daily maintenance.

[0033] More specifically, the spacing between the pre-embedded anchor bolts 3 and the track connectors 6 should be in accordance with the equipment installation requirements. The width of the precast concrete base 2 can be determined in conjunction with the lateral spacing requirements of the anchor bolts, and the height of the concrete beam should meet the anchorage length requirements of the anchor bolts. The anchor bolts can be U-shaped or straight.

[0034] Specifically, the top surface of the precast concrete base 2 is provided with a secondary grouting layer 8, and the track 1 is connected to the surface of the secondary grouting layer 8. The secondary grouting layer 8 is typically made of 30-50mm thick cement-based grout. By setting a secondary grouting layer 8 between the track 1 and the precast concrete base 2, the flatness of the track 1 installation is improved.

[0035] Specifically, the length of the hole in the oblong-hole track connector 6 is 3-5 times the diameter of the pre-embedded anchor bolt 3.

[0036] Specifically, the distance between the precast concrete base 2 and the side wall of the reserved groove is 120-150mm. The specific distance is determined based on the maximum horizontal deformation generated under material loading.

[0037] Specifically, the spacing between adjacent timber beams 4 along the length of track 1 is 500-800mm. The spacing of timber beams 4 can be determined by calculation based on the material of timber beams 4 and the horizontal load, which facilitates on-site installation, horizontal adjustment, and ensuring the tightness of timber beams 4.

[0038] The implementation process of this invention is as follows: In the pre-reserved groove of the stacker-reclaimer foundation 5, a precast beam leveling layer 9 is poured, rubber pads 7 are placed, and then the precast concrete base 2 is placed in it. The installation of the precast concrete base 2 is aided by the positioning of the pre-embedded anchor bolts 3. Timber blocks 4 are placed at certain intervals on both sides of the precast concrete base 2 to provide support. The track 1 is fixedly connected to the precast concrete base 2 using the pre-embedded anchor bolts 3 and track connectors 6, ensuring that the track 1 is within the allowable installation deviation requirements. The installation of the track 1 is completed by pouring a secondary grouting layer 8.

[0039] The adjustment process in this embodiment of the invention is as follows: When track 1 experiences small displacement, routine maintenance of track 1 is performed by adjusting the track connector 6 with the elongated hole. When track 1 or precast concrete base 2 experiences large displacement, the original timber 4 is removed, the position of precast concrete base 2 in the reserved groove is adjusted, and after track 1 is straightened, timber 4 of appropriate size is inserted to complete the adjustment of the lateral deformation of track 1 and straighten it.
